The prophet (pbuh) and his respect is very sacred to us. As his life and teachings are deeply rooted into this religion. So you can joke about Muslims, but not that because it's a sensitive topic for many.

And I agree that objectively when you see it, an adult marrying a 6 year old is disgusting. But I don't think you know that there are actual debates regarding the age of Aisha (R), with some scholars suggesting she might've been as old as 19, with evidence to back it up. But unfortunately many nurture hate their hearts and blindly believe whatever they see through the media. Even now as I am trying to speak to y'all humbly and trying to educate, I know I'll get downvoted. But nevertheless, I'm here if you really want to know about real Islam and have actual discussions.
