Many seminary programs do not teach enough of the organizational/business management side of church.

That could happen if you follow David Hogg's and AOC's advice. Get rid of the old guard that is only good at getting Trump elected.

My parish used to always have a booth at Rainbow Festival, but it and Phx Pride have both gotten very expensive. Now we do Melrose Street Fair.

I am curious, where does this place Old/Independent Catholics, in the same category as Roman Catholics or under Other Christians?

I saw it a lot in PA and here in AZ, especially among ELCA parishes. My parish (Independent Catholic) is mixed (parishioner preference).

Self-intinction is very common in my experience, especially in the churches I frequent.

Thomas Ken's hymns have been in my memory for ages. I heard them all of the time in the Presbyterian church as a kid.
