Isn't this an example of what the Original Poster is complaining about ?
He feels the need to leave because his posts were beat on, and now we have people reviewing all his posts and telling him he's wrong for feeling that way.
Who knows what may have happened in Private Messages, or what the OP's sensitivity level is. Harassment is in the eye of the receiver.
I understand, I only post about once a week now for similar reasons.
One small point...............It's only a forum. If posts get you that upset, then the OP has the right solution. Better to stay away from these posts and live in the real world. It's way too much work to get into an argument in cyber space.
After all, if your post count is higher than your mileage, then even with the best of intentions, some of your posts are bound to insult someone or other.
