Religion?

It'll be hard. Especially when you get the pro-Muslims, they'll rage if some user provokes their religion rules, laws and mindset way of living. Plus you shouldn't be representing any posts about religion on behalf of your forums or you're likely going to get spammed with hate messages.

IMO God is just a supernatural-like defined word in religions, where they have to pray and offer them sweets, money, food, etc to get their blessings so you'd always have good luck. It's an important part of a religion, FYI. Human's oldest and undiscovered answer is..

"Who is God?" Who can also be a what, but to some people it'd be disrespectful so yeah!

Good luck!
