3rdeye-
1.) some things are not clearly jokes. Racial comments can really cross the line, even though we all try to have a good time and joke around on this site, I can see where the comments you made could be offensive to many and I tend to agree with the sentiments regarding those posts
2.) as far as "Ultimate Ass" threads go, there are a couple things to consider: a.) Eddie created it. He's the boss. b.) while there is an inherent sexual innuendo implied in said thread, there was nothing overtly offensive such as talking about brown (insert word here) women in Texas, or referring to certain ethnic groups as "chimps" and other derogatory descriptions.
It's one thing to have a post admiring beautiful women, it's another to speak badly of them, or refer to them or ethnic groups in a way that may be considered a slur or insult. I guess you can say it's a fine line between having fun with a concept, and crossing the line to where it becomes something insulting, demeaning, and inflammatory. I would recommend just thinking it over a bit before posting. However if you really don't care, that's your prerogative.
