A person, who ignores malnutrition on the rest of the planet, and tries to force his/her own view on others. Often seen protesting medical advances, clothes or food that involved animals in the process. Would rather "convert" people to his/her own beliefs than accomplish something productive in life. Often resort to drastic action for attention, because their "cause" is not important enough for normal people.

Hypocritical asshole who thinks that he/she can stop the killings of "poor, innocent animals" by harming humans and being a bitch until they get their way. In other words, someone with smaller intellegence.

A BBC website put it best:

The press often confuses animal activists with animal extremists.

Animal activists live their lives in an animal-friendly way and use only conventional means to promote the animal cause. These include:

Diet

Not eating animal products

Shopping

Avoiding products tested on animals
Avoiding products made with leather or fur

Living in an animal friendly way

Avoiding pesticides
Avoiding products that harm the environment

Education

Learning about animal issues
Teaching others about animal issues

Entertainment

Avoiding zoos and circuses

Investment

Investing only in companies with animal-friendly policies

Politics

Lobbying for pro-animal legislation
Campaigning about animal issues
Telling other people about animal issues
Writing books and articles about animal issues

Terrorist who is a fanatical fascist and may be a memeber of peta, alf, elf, the humane society, or any other domestic terrorist group. These people have been in the city too long and either have brain damage or think Disney movies are real. They enjoy blowing up fur farms, fur factories, restaraunts, banks, stores, homes, etc. They see animals and humans as equal, which means they have all fallen away from God's Word, and are ignorant of Genesis 1:26. peta's elite propaganda members like to put out sexually immoral and sexist items to grab peoples attention. They also try to shock people into believing them by feeding them lies. Basicly, don't trust them or make any eye contact. They've been around animals too long and are now starting to sport animal-like behavior. Especially that ugly woman, Ingrid hitler, or whatever her name is.

Normally a preachy, whiny person not unlike the very religious people that wander about trying to shun the extremists of their creed while painting themselves and their crusades as moral and just even if it means committing immoral acts such as dishonesty (see definition 11).
Often found on any form of media that allows them to voice themselves no matter how ignorant, hateful or repulsive the remarks they make.
Most often they are young, white teens in well off enough backgrounds that they never had to experience a lack of necessities, thus they are often very opinionated, will blindly support anyone they feel is serving the cause and will not research beyond what they feel is right (ie when they free animals sheltered in society and leave them to die trying to survive on their own).
The more extreme of the line tend to value animal life over human, unless it's themselves, and will stoop to any level to continue their "moral" crusade. There is no compromising with them, they feel they know more than everyone else, will often tout their veganism as their evidence they know more, and will shout down or coerce others through violence (See Sea Shepherd).

the only way to deal with them is to ignore them and within a short period tend to grow tired and leave as their moral crusade tends to come and go in surges much like fads.

A practice & philosophy of compassion to all animals & to stop cruelty to them based off human exploitation........nothing more, nothing less. The rest is off-shoot branches of the movement that differ in method to achieve the objectives & what constitutes exploitation (see veganism etc).

Usually hits a nerve with people who aren't animal rights activists & makes them feel uncomfortable & so they slander the movement often without being informed, instead basing their opinions on stereotypes.

A person who speaks for those who can't speak for themselves(animals), fights for those who can't fight for themselves and defend for those who can't defend themselves.

(Let me start off by saying that I find the definitions that are listed here to be very offensive. I am a vegan and a supporter of animal rights. I am also very active in human rights, peace and social justice activism. It is a fundamental misinterpretation to say that people who believe in animal rights hate people. For the most part, animal rights activists are very concerned about issues related to cruelty towards humans as well as non-humans.)

An animal rights activist is someone who cares deeply about the fundamental rights of other living beings, believing strongly that no animal, human or non-human, deserves to suffer. A core belief of the animal rights movement is that sentient beings have the right to live a life free from cruelty and exploitation. Animal rights activists do not seek to create a world where non-human animals are treated better than humans, rather a world where no sentient being, including humans, has to suffer. Many animal rights activists are also active in other communities such as human rights activism, social justice activism, civil rights activism, peace activism, etc.

Animal rights activists seek to reduce or relieve the cruelty inflicted upon other sentient beings.

People who respect every living creature on this earth.No they dont value the life of a human more than a cat they are both equal sentenint beings that deserve to live.Some of the definitions here are so fucking clueless.By the light of me I cannot fathom how some of these idiots think that what some stupid religios book says goes.You have no right to think that you are better than something just because you're believes tell you.Of coarse I would bomb fur farms.You asswipes have no right to kill animals for thier fur especially since we have more fabrics that dont require animals.By the way fuckers I donate both to animal shelters and to poor starving children in africa what have you idiots done?Sit on you're fatasses and complain about animal rights and how we should worry about other things?Oh well I guess some fat idiot eating 4 double bacon cheesburgers daily that lives in kentucky knows better huh?
