There's an atheist organization called "Sunday Assembly" that meets once a month in a similar-to-a-church fashion, where they have a speaker, songs, and community events. My understanding is that they are tax-exempt as a non-profit, but I'm not sure if they have any sort of religious status. Some friends of mine were discussing checking it out next month. Many non-religious folks I've encountered tend to lean pretty far to the left, so they may actually try to prosecute if I'm caught carrying. Thoughts?
