I thought I'd start out with an easy topic that couldn't possibly cause any controversy: Religion!
Whoa there, cowboy, get back here. I promise this won't be too terrible.
(And now I shall spinelessly hide behind a disclaimer that I know will do nothing to stop angry commenters.)
*~Friendly Disclaimer of Groveling Friendly Friendshipfulness~*I do not claim to be right about anything. I don't know shit, and fully admit it! I fully believe everyone is entitled to their own opinions about religion, spirituality, et al. If I say anything that offends you, just tell yourself, "This Jess chick is talking out of her ass (a thing she is wont to do). Jess is a stupid [insert sexist or gender-equanimous slur of your choice] and nothing she says can shake my faith. I pity her for having literal used urinal cakes for brains."
Now, that that's out of the way, let's get to the shit that'll probably piss people off!
