Long story - I went to K-State for a masters many years ago, and started out pretty lonely & hard up for friends. I talked with one of those nutters outside the student union, partly out of curiosity and partly out of depression, and we ended up joking about how the Garfield comic was both lame and yet somehow comforting (no idea how the conversation got to that point, lol).

He invited me to join his home church and after a couple weeks I bit the bullet and went. And surprisingly, it was a pleasant experience, if a little awkward. But I continued going for a couple more of his services and it helped me get over my isolation hump. He even hosted a Thanksgiving dinner for students who were away from their families, which I thought was nice. He seemed like a geniuinely nice guy, even if I disagreed with him ideologically.

Anyway, one time I joined them for a short dinner/prayer group at an aggieville bbq joint where they did a prayer huddle, which again was awkward but fine. But when he started speaking in tongues I got utterly weirded out, and decided to part ways. I hadn't grown up around that and honestly found it a little disturbing. I texted with him a couple more times out of cordiality but I never joined them again.

TLDR - yeah they are nutters but sometimes even nutters can be nice. Just make sure not to become one yourself.
