In DC, you’re nearly as likely to find a Trump-hating, pro-abort, radical leftist hag in a church, especially a Catholic church, as you are in a bar favored by DNC drones.
But there are supplementary locales.
If one is looking for nice people, they can probably be found, even if not everyone is nice. There are a few people in my own parish that I don’t really like, but many more of whom I’m very fond.
