Hah.... Problem is, for the nuts that do this it doesn't matter if the animals live or die. Either they're "saved from a worse fate" in the lab, or it's "the scientists who made them like this" so their existence is already unnatural or they're even "martyrs to the cause", but it's a flimsy justification for wanting to bust up someone's workplace without running into the level of security to be found in the average factory or office complex.
Ultimately, it's not that they like animals. It's that they hate people.
And I'm not exagerating, last year, in a spanish 'animal lovers' facebook group named F.R.A (you can verify it by yourself), a girl told the rest how 'good person'was an old lady, who beat up his grandson (who was just learning to walk) after being bitten by the house's dog, she produly told the group that 'no question was asked' and she inmediatly figured out that the dog was innocent.
And many cheered it up!
Even in youtube videos, where little children got severely injured (look for instance, "perros atacan niño", there are comments accusing the victim that 'the kid must have provoked the dog, dog's won't attack without being provoked', and when I ask them to watch videos in youtube, like "Dog attacks Police Officer Taser Full News Report" they get angry, and many of them say I'm a nasty person, and that they refuse to watch the video.
FWIW, they openly say they prefer animals than humans, they don't bother to deny it.
Would you feel well, if you realize some of these individuals, is near your children on daily basis? Shouldn't PSYCHIATRY already have noticed them? Or are there studies of this mental illness that Im not aware of?
