In tussia many Vegans and Animal Rights activists are unfortunately anti-porn. Some of it comes from the strict Straight Edge culture dominating that spectrum of society. Unfortunately many of these people also believe that LGBT people are ill and need to be cured.
On Anarchopedia (anarchist wiki) there was also an individual who went on the vandalism spree deleting any mention of sex, sexuality, porn, erotica, and everything else. Who was a german anti-speciesist. But in germany there are a lot of right wingers who have joined Animal Liberation movement.
In in england right now, and it's much much better here. q;-)=
