Being a youth minister in an SBC and having been SB all my life, and attending a GB (General Baptist) college I must say that Baptists do have a LARGE list of do's and don'ts. As a whole, the church I serve in doesn't say silly things from the pulpit, but the individual members can be pretty legalistic.
A funny story about that was this one day at school. The night before, I had had a pounding headache and wasn't where I could get any headache medicine. I was with some people from a church I used to attend at a Buffalo Wild Wings and I ordered a strawberry daiqari. My headache went away by the time I'd finished the drink. Well, I was telling someone in my New Testament class that I'd drank that and such and someone turned around and goes, "It was virgin right?" I said, "No. Why would I do that?" Some other people heard the story and such and I got a lot of dirty looks and I think someone even said I'd killed my witness by drinking that. The only people who gave me dirty looks, though, or made comments were the Baptists of various sorts in the room.
Anyway, I must agree that, from my experience, Baptists seem to have way too many do's and don'ts. I'm not sure about more than any other group, but they do have a WHOLE lot.
