Here are the reasons why i wouldn't join some of these
Children of Atom: Why would i want to worship nukes when most of them died out centuries ago? clearly they are loosing power. the gods died, and we killed them
Curch of Bacon: Bacon is close to Ham and i swore never to talk to htat guy again after he offended my friend Noah
Spaghetti monster: I'm pretty sure i would be considered a heritic in this religion, as i have been eating god more or less every week of my life since i gained teeth
Jediism: As cool as it is, i don't want to be ostracised because of my love for sand
Klingon religion: I'm not into Klingy people
Ciult of cuthulu: Lovecraft was a massive racist and anti-semite. No joke
