Of the 1,000 or so posts I've read in the last year - including his hundred or so OP's - it is crystal clear that Rug's work is overwhelmingly critical of, even personally insulting to, atheists. (Even if his authors quote or are atheists themselves, Rug quotes them primarily only when they are being self-critical. Critical of atheists.)
Today of course, computer searches and search technology, combined with simple sociological research tools, could fairly easily rediscover all of Rug's DU and other quotes.
And from that, the pattern should be clear enough: Rug long ago launched an unrelenting, one-sided attack on atheism. One that now extends to fully 60,000 posts; and probably a thousand negative re-postings of other anti-atheist articles.
Moreover, Rug has not been shy about simple, childish name-calling. Here he calls Dawkins an "ass." And he chooses to re-post an self-critical video by atheists, telling them how not to be "Atheist Assholes."
It seems to me that anyone that wanted to can, with just a little semantic sophistication, easily demonstrate some unpalatable things in Rug, and his posts. Just a little semantic awareness, would be enough to start sustaining alerts against him.
Calling him on simple name-calling might not quite be enough. But that will be our first step.
