Physicsgirl is right. I've had a bunch of posts deleted where I very carefully avoided "language" and anything that could possibly be construed as an "attack" (something I don't do often anyway). All I did was disagree with either a poster or the writer of the article and gave reasons why. Every single post was deleted within two hours. No, this is a capricious editing process, and not only is everyone expected to agree at all times with no dissent permitted, certain people are being targeted for deletion. I'm not the only one that's noticed this.
