The
link provided by entertainme is actually a very interesting read. The head of PETA sounds insane. She calls human breeding, vanity (she sterilized herself at age 22). They don't care about the feelings of people (the example about using Heston's disease as a tool for propaganda).
It is good to fight for animal rights so they don't get tortured, but going to the extreme of bombing research facilities is definitely wrong.
I have grown with pets (or as PETA calls them, companion animals) all my life, I currently have 4 dogs and I love them very much, so I care for animals, but doing research on animals is important for medicine.
The president of PETA from her quotes and from her actions seems on the fringe of society.
