In a nutshell, this is my observation:
Those who have an honest MT TEND TO never again be seen dancing together, holding hands in public etc. Those who don’t are MORE LIKELY to (doesn’t mean all of them do) go to mixed weddings with mixed dancing, “mingle” at kiddushim that tend to be mixed. One thing I have noticed is that when in a Chasidish shteeble and they make a mishebairach for cholim, they mention men and women in one mishebairach, while at the less Chasidish shuls (e.g. Young Israel I daven sometimes in the morning) they are very makpid to make separate ones for men and women.
Granted, I have not been all around the world, and have been to less chasunos than most people here. But these are true observations in my life and my surroundings.
