Leave comments enabled and unscreened on all posts, or don't post at all. It's in the rules. This community isn't your private soapbox. If you want to post something and get no dissent, post it in your own journal and censor your commenters to your heart's content. If you post here, be prepared to deal with people's responses, or delete the entry if you can't take the heat.
Good christ, people. I realize that as the membership of a community goes up, the average IQ drops, but there are six simple rules on the userinfo. Read them, love them, follow them, and if for some reason you still just don't understand what they mean, perhaps some remedial reading comprehension classes should be a priority for you before posting in this community.
