Ever been banned from a web forum?

Hey guys... Thanks for the responses. I appreciate the words from everyone, even those that disagree with that I have to say.
One person here has an anti-Obama reference in his signature. It was THAT sort of thing that got me this last time.
There was a post about high gas prices. My response was....Many experts say that the White house has little responsibility in regards to gas prices, but I'd be willing to pay $5.00 per gallon if it sends the man back to Chicago." Although it may seem very tame to many people, I felt that I may have crossed the line afterwards. The next morning I woke up with plans to edit the post, but found that I was blocked. I should have listened to my instincts. I've been banned before. One seemed so stupid I'm still amazed by it. A thread was up that read..."Whats the fastest or stupidest thing you ever did?" My response? "The fattest and stupidest thing I ever did was named Michelle." I really thought that it was funny. Its amazing how what one finds hilarious can be totally offensive to someone else.
