They have been endorsing candidates, sure.

We are members of the local YMCA. They have a gym, swimming pools, sauna and health classes. The YMCA is a non-profit, like a church. Our membership dues are not tax-deductible, of course. Why should a church membership "dues" be different? They shouldn't.

We once were members of a very liberal church. Not evangelical, upper middle-class. This church spent less than 5% of revenues on charitable causes. The rest of the considerable revenue was spent on facilities upkeep and salaries. It's a social club.

The church members wanted to redo the parking lot. I said if we really followed the teachings of Jesus, we would take a wrecking ball to the whole thing and build affordable housing or something and meet in a local school on a Sunday. They redid the parking lot.
