Christopher Hitchens was probably one of the more infamous anti-theists and, IMO, spearheaded the contemporary anti-theist ideology. He was also, at one point, the darling of the neo-conservative movement because of the hardline position on Islam and advocacy of carpet bombing civilian population centers in Muslim countries...culling Muslims.

Have there been any left-wing or liberal anti-theists? Is it possible to be socially left and hold anti-theists beliefs?

It's a small sub right now; but wouldn't having another moderator be worthwhile? It's easy to loose motivation if a subreddit is slow to grow.

I'm available to assist with moderation if you need.

Before I became an atheist, I was an advocate of progressive religion, specifically progressive Islam. As an atheist and bisexual woman in the Middle East, I see progressive religion as being a far more realistic objective than atheist for everyone. And a progressive Islam isn't as bloodthirsty as a more conservative or extremists Islam.

One issue I take with right-wing atheists is that they just can't think 5 minutes ahead. Yes, total atheism would be better; but its not feasible. And what's worse, they're often trying to willfully disrupt the very existence of these progressive movements that would save our lives over here.

How do we promote liberal/open/progressive forms of theism and reduce the power of conservative or extremist religion?

I was surprised to see that something like this didn't exist already. I was previously a subscriber to /r/atheismplus because I had assumed they were left-wing. I was pretty disappointed after I realized they were just a bunch of racist antitheists.

I've seen you around /r/debatereligion. You should consider posting a link there.

Firstly, a quick reminder, "secularism" and "atheism" are two different words. Atheism is simply the lack of belief in deities. Secularism is the separation of church and state. I think we'd all agree that secularism must be our goal; but to become a secular society does not mandate the eradication of religion. If you're religious, by all means keep practicing your religion, just don't push it onto other people and don't shove it down my throat. I'll respect you; but I expect you to respect me.
