I can't comment on "psychologists" in general, but at least around here we'll only spend a few days talking about it before it disappears to the bottom of the thread list. I personally appreciate the back and forth, especially when my own beliefs are challenged and I'm force to either defend them logically (both to myself and others) as well as change them as needed. This is a relatively safe, relatively anonymous forum, moderated so as to not get overly off track. I think it's good to have this available, as most of my actual work as a psychologist is spent with mundane stuff or more complicated clinical issues, without much opportunity to discuss the more philosophical, non-direct clinical stuff. I also think that are profession does get somewhere, despite these type of things popping up every now and again. Hell, just in the post is was pointed out how we have moved from the categorical approach (that was de rigeur in CBT training when I was in graduate school) to a more process-oriented approach. That's getting somewhere. Debates in our field will probably always mirror the prominent debates/issues in society at large, but the day-to-day stuff still moves at the pace of the research and clinical innovations.
All that said, I think the current main issue is pretty straightforward- don't say the g** d*** N-word in public unless you are looking for things to get pretty uncomfortable for yourself, whether or not you, your mom, your guru, your best buddy, an anonymous poster on a message board, the past of future president, or anybody else thinks that fair.
