Is it worth going over there and looking?
VanDeKoik described it well enough. You can probably find any subject under the sun discussed there. Just search a word or subject and there will likely be a subreddit created to discuss. If not, they encourage you to start one. There are plenty of religious, military, gun-owners, etc groups. You will of course be able to find every decadent, fallen subject under the sun as well..some that you might have never imagined. Just search carefully, and click thoughtfully :)
