Offhand, I can’t think of anything I hold sacred. I think everything and everyone can be made fun of, but some things can still be inappropriate. An example is a bit of useless knowledge I saw today:
Now, I’m not a fan of the Mormon faith, but that was an inappropriate cheap shot. It’s also misleading. “More than many” would seem to indicate that a sizeable number of Mormons have over 100 wives. Plus, I think by the time you’re up to 100 wives, you’re no longer a part of a recognized religion, you’re clearly in cult leader territory.
