Being a Republican on Atlas isn't hard; members like Badger and TD are pretty well liked and respected. For example, TD and I disagree on a lot of issues, but I respect him and appreciate his contributions here; same with Badger. However, being a Trump supporter or a social/cultural conservative does seem considerably more challenging. The forum is disproportionately secular and liberal, which results in a rather widespread hostility towards Trump's brand of politics and socially conservative viewpoints. It doesn't help that most (but not all) of those contributors here are walking stereotypes.
Honestly, I'm always surprised by our number of religious people.
