At www.revleft.com leftist forums. I quit going there because of discrimination towards me because of my religion. one of the mods is a militant atheist and also claims to be an anarcho-communist. However, I found that he was more like Stalin than anything else - peace, freedom and equality are important to him...but only for those who he deems worthy. I was friendly initially, and I made the mistake of claiming on a thread that "We're all on the same side here". I got flamed with some of the most discriminatory things I've ever read, that apparently I can't believe in the philosophy of communal living because I have a religion. In the words of Yahtzee:
"BULL.
FUCKING.
SHIT."
It turns out that there are fascists where you least expect them to be. It's like he was a Nazi, but hating not just Jewish people, but everyone with a religion. Oh, and most other forum-goers there proceeded to post pictures of burning churches and out-of-context, extremist interpretations of religious texts.
And before I look like a whiny troll, I could post quotes from Marx, Engels, and Lenin that support my side of this. And I will, if requested.
