I don't think Blackcatter has been abusive at all. Pretty thin-skinned, there, GUEST (whichever GUEST you might be).
I more-or-less understand why someone would wish to be anonymous. I consider myself anonymous all the time, since I don't use my real name. Anyone who reads enough of the threads I post to can, of course, form an idea of my identity, and I am content to let *everything* I see fit to contibute be a part of that synthetic personality.
My only problem with reading "guest" posts is that I can't tell when they're from different individuals vs when all the "guest" posts in a given thread are from the same person. It's difficult enough to keep the different voices sorted out when the "From:" line is properly completed.
