I have to agree with you, Hopinso. I find the avatar offensive on many fronts. For one thing it reminds me of the thing of a few years ago of the photo that Jesse Helms got so upset about. Remember the guy with the same outfit with a whip inserted in his butt? Tried to pass it off as "freedom of expression". Maybe it was, but it seemed to me that it was done for attention or to aggravate lots of folks.
If I wanted to view those type of photos, I would go buy a gay magazine or maybe a motorcycle magazine. Maybe there are some on the internet. I do not know. If S S likes that thing, more power to her. Just do not try to force it on others.
Sometime back someone had an avatar of big boobs swirling and many folks found it offensive, even though the poster loved it. He did take it down for respect for other people. He sure earned my respect by doing that.
