Just recently, we had a time of musical worship at church on a Saturday night, and during one of the songs, I raised my hands and sang. I was called out on it by a fellow Baptist friend that I had "gone charismatic". I don't think raising hands falls into that category. Raising hands is, as has been shown, a command of Scripture.
I do agree, too, that there is a time and place for it. Some places it would not be appropriate, and etiquette will show you when those times are I am sure.
