I get this, Paul . . .it seems that you've been where you are for at least a couple of years, right? You probably had a month or two at the beginning there, where you and the people around you were trying to get to know each other . . .you put out feelers, listened for flaws in judgement, got to know in/outs of relationships. That was the danger time when your self-described "big mouth" might have gotten you in trouble. But after you've been with a group of people through a crisis, a holiday, some awkward moments, then we all make allowances for each other. Everyone who really knows me would never consider bringing up certain subjects (like woman in the church.). It's really a kindness for us both.
Here are some ways to test out your theory of NTM being a place for free spirits: oh, you didn't say that? Sorry, my mistake

.
1). Bring a beloved, free-spirited friend down to do a project. See what kind of assessment they do on her spirituality.
2). Go really out of your comfort zone on a social project
3). Bring along a LGTBI friend
4). You get the point . . .
Still friends?
