Your question is now reopened, so point 1 is done! We are still waiting on point 2.
I self-identify as liberal - though I do believe in the resurrection and hence I'm not "extreme liberal" by your question's definition. There are probably more people here than you think who have liberalish views, on some axis or another. My impression of our more conservative users, by the way, is:
- We don't have a lot of presence from "extreme conservatives" (whatever that means - but I think the conservative opposite to "extreme liberals" would be much less mainstream than the conservatives I see here).
- They are decent folk who are as scrupulous as anyone when it comes to maintaining the site standards, voting on the basis of quality rather than agreement with content, and treating people with respect.
This is based on over two years of being here, and accruing over 11k points of reputation while publicly identifying as liberal and generally answering from that standpoint on questions where it applies.
It's true we have occasional problems, but somehow we muddle through. For your question, I see that there's been discussion in comments, editing of the question to make the scope more obvious, and clearing out of answers that didn't fit. I hope that you will get a useful answer to your question (currently at +3 net votes, which is good!) and that you'll stay around to ask and answer more good questions.
