As someone with a handicapped individual in the family, I understand Jim's concern about the walkers comment, however, I believe that the intent of the post was made as a jest as to the age of concert goers rather than an attack on the handicapped.
And yes, the comments do get sexual, and after awhile, it gets old. I believe it is meant in good fun, but this is a public forum, and family members of all ages do have access to all but Cartoon World and Ecstacy.
As a both a model and a writer, I am quite comfortable with both my body and freedom of speech/expression.
Restoration comedy is one of my favorite literary eras, and it is quite bawdy and licentious, so "comedy of manners" topics fail to offend me. But, it has its time and place.
My suggestion is to use some discretion so everyone feels welcome.
Maybe some of our female members may return if the fraternity hijinks mellow.
