Vegan terrorists are an extremist sect within the vegan movement who fundamentally believe in the same principles of animal protection and liberation as other vegans, but resort to violent measures to pursue their objectives and prevent animal cruelty. These include vandalism of animal farms, destruction of animal testing laboratories etc. An example of such a movement is the Animal Liberation Front (ALF), which is an international leaderless and decentralized movement classified as a domestic terrorist/extremist threat in the US and UK respectively.
