Why?

Because these people are evil. Today it is fashionable to pretend evil does not exist. One definition of evil is a lack of empathy. Tremendous self interest and selfishness usually accompanies a lack of empathy for other people.

They DO HATE HUMANS. The whole animal rights/liberation thing is about self hatred of humans. Not elevation of animals, a devaluation of human kind.

Again why?

Because they love themselves, but they also HATE themselves. And their own pathetic existence. Depression. And as a result HATE their fellow man.

The internet facilitates their self love, all the pathetic superficial selfies. It als creates a shallow superficial existence without foundation. Depression and self hatred follows. This angst is directed against ther fellow man. They "love" animals, therefore those that "harm" animals are hated. The internet facilitates their shallow weak nasty attacks as they can be done anonymously and without being face to face to those they want to insult. Pathetic weak shallow superficial spineless cowards.

I try to deal with people as if they were on telephone, or face to face. How often when I spreak to a troublemaker on the forums on the phone (two or three times have done this), how obvious they are by embarrassment by their behaviour even if it is never mentioned on the phone. How a direct telephone conversation is entirely different in their minds to an "anonymous" internet post. And face to face is even more so. How many Boards and Committees can have even enemies dealing with each other, in a polite manner, because that is what works and angry internet type tirades do not work. The opposite. How pro gun internet experts have no idea of either, because they never actually have to deal with the "opposition" and "middle men" face to face.

Enough off topic comment by me ...
