I often post in Guest mode simply because I'm not on the home compooper for most of the time. I'd hate to lose the priviledge because someone thought that was wrong. I'm the same person, Guest or no guest in front of the moniker.
I think some of them "get disappeared" not from expressing their points of view, but because of an excess of vitriol and heat about their point of view. Also because they apparently have the time and the will to try to dominate the thread and will carry on flame wars within and without the thread.
All of this having nothing to do with this thread of course.

To bring it back in line, I noticed a politician doing exactly this same thing, diverting from the question asked to answer a question that hadn't been asked so that he could pound one of the two candidates.
