I decided to post a short explanation as to why I locked the thread, without going into the various individual posts above. I intended to post this in the Elvis thread, but events (like this thread) overtook that intention.
I watched the direction the Elvis thread was taking with growing concern, in particular when I read the Elvis/Wagner/concentration camp analogy that was posted in another thread and the reactions it provoked in the Elvis thread. In my view that analogy was way over the line and uncalled-for, and to prevent the thread from going down that line any further I locked it. However, having thought about it and realizing that some of the reactions in the Elvis thread were civil, balanced and thoughtful, I re-opened it.
As this is another clash between the way I am moderating this board and the opposition it seems to generate, I decided to take time off for personal reasons. So it's goodbye for now.
