I don’t agree. There is nothing for people to do that is culturally acceptable to most of these young adults.
they did not grow up in a church culture.
Not the Masons, Elks, Kiwanas either.
they don’t want to spend their time in bars.
Not the Legion.
There is no place really for them. Cosplay is their version of the Legion hall or the bowling team.
They have plenty of places to go. And when they lack one they make one. They make their own clubs, own events. Heck they probably have a stronger community than most of the old “lodge” type places have in years.
