No matter how tempting you may sometimes make it. But while I am regularly extremely critical of the positions other people adopt, I very seldom slip as far as personal attacks, and I do not resort to profanity, even in extremis.
I don't bother to post agreement, in general - if someone else has already said something worth saying, I don't bother saying it again or slapping them on the back.
However, looking at my posts in this subforum in the most recently-modified threads, in
http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=229&topic_id=3921&mesg_id=3921 someone else agreed with me (and I also broke my rule about not chiming in, for once). Likewise at
http://www.democraticunderground.com/discuss/duboard.php?az=view_all&address=229x6696#6701, although in that case the people agreeing with me were ones whom you probably also categorise as "disruptors" (i.e. people who don't agree with you), and at
http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=229&topic_id=6764&mesg_id=6764Aha, got one. At
http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=229&topic_id=6764&mesg_id=6764 I posted to highlight a subsection of something someone else said that I thought deserved to be given more attention.
If you do measure the value of a contribution by the willingness to walk in lockstep - which strikes me as a foolish way of doing so; the most valuable posts will be the ones saying things no-one else is saying (although the reverse is not true; they're only a subset of those) - then it's clear that there are non-trivial numbers of other people who agree with me.
But in general, most of my posts on this subforum, and on the internet in general, are when someone has said something I disagree with.
How do you define a "detractor"? My suspicion is that your contention that "ideas are welcome but detractors are not" is a mistatement of the purpose of this subforum as viewed by the moderators, but I'd need to know what you meant by a "detractor" to be certain.
"I will not rebut or attempt discussion with those who make it impossible to discuss reasonably." Wonderful. I'm very happy for you. I, however, don't make it impossible - I set out my positions, and explain carefully why I think they are the correct ones. That makes it very easy indeed to discuss reasonably.
