Newsflash!? Really? If one wanted truly to encounter the "abusive nature" of some of the lefty netroots, try posting as a conservative on the Huffington Post web site. The profanity, even the obscenity, of the vitriolic denunciation that fills one's email box after a post is almost unbelievable.
Let's hope the internecine warfare on the lefty side of the web will alert the well-meaning people there that there's a real problem with the way some of their less-polite compatriots conduct themselves.
