My point is primarily that calling a group like the ALF or SHAC terrorists, freedom fighters, or neither, is a matter of perspective, not solely dictionary definitions. To those who profit from animal torture, property damage to lab equipment and buildings is terrorism. To those who believe that animal tests are unnecessary, horrific, and morally repugnant, property damage to torture chambers is a compassionate act of freedom fighting. To one side they are the enemy and to the other side they are the heroes. If you are a researcher, you despise them. If you are a tortured animal (and know what they are trying to do for you), you love them.
Personally, I would never do any property damage, not even minor it is not in my nature, but I do not condemn it either, given my knowledge of the extreme violence and torture inflicted on helpless victims for no good reason. I will just continue to bear witness and write about how horrible animal testing is and how ethically blind researchers are. It is my deepest hope that all property damage and animal torture end as soon as possible. Until then, I will keep writing and speaking as a non-militant activist / advocate. What militant activists do is up to them.
