I have regularly attended Methodist services in the past, and still enjoy attending Anglican and Methodist services occasionally. I usually describe myself as an agnostic with an emotional attachment to Christianity.
I have had the same experience as PaulJ, when I attended a wedding at a church which is Methodist but with a strong "born-again" atmosphere. I use "born-again" as a label for the arm-waving, singing with your eyes closed, kind of worship. I actually think that being born-again is implicit in being a Christian of any flavour, but that is another argument.
I felt really uncomfortable with it. Maybe it is because I remember those kind of people as being the only ones who were ever really vicious or nasty when I was a door knocking JW. Atheists were merely dismissive in a quietly amused way.
Ironically, I also observed that the service was full of the misogyny, dogmatism and cliche of a JW wedding service! Double nausea. I haven't felt like that in any Anglican or other Methodist wedding service.
It goes to show that there is a refreshing difference in congregations of the same denomination even within a small area. Another Methodist congregation 5 miles down the road will be completely different. If you enjoy the more demonstrative kind of worship, it's there; if you like the hymns to have tune, and you don't want to hug the person sat next to you, there is somewhere else.
Interestingly, the wedding was for the man who had been my husband's best man when we married. They had been friends since they were small children. He chose one of his wife's friends (who also attended this church) to be his best man, and we haven't heard from him since the wedding.
