It’d be more accurate to have it say “I’m offended that I wasn’t taught proper history, and think that a painting by a gay man was the first, only, and accurate depiction of something that potentially never even happened”

Apparently it’s not the Last Supper but even if it was, what part mocks Christians? Like nothing in the stage direction is mocking, so it must literally just be that they don’t like drag queens.

A drag queen performing a Queen song isn’t mocking Queen. They just are a drag queen while performing Queen. I wouldn’t be offended by that as a Queen fan.
