Kimmio, if I were doing a really bad job of defending a cause, would you tell me? Can you think of a cause that I defend that I do badly? If so, please tell me. I'm a little sick of you constantly dragging up chansen's comment.
A bad defense of an issue can do it real harm if it reaches the wrong audience. You have a tendency to get over-emotional, under-rational, and post wildly unfair accusations against people who even try to probe your opinions.
You are not a very good advocate for the disabled. You put people off with your retreats into victimhood. No-one wants to hurt Kimmio's feelings, but we all do, constantly, no matter how nicely we try to disagree. It certainly doesn't do anything except to re-affirm the weightier aspects of total inclusiveness.
So there, I've said the same thing chansen did, but a little differently. Bet it's no better received. And you still haven't explained your "Bette, of all people" comment. As if I'm specifically unsuited to having an opinion...
Finally, yeah, I think you should take a break. You don't seem to be doing very well with even reasonably robust arguments, yet you keep on wading into them.
