To their credit, in many countries where circumcision is common there's a lot of misinformation about uncut penises, and a general taboo around talking about penises in general. The whole "uncut penises are unclean" thing is a common myth which appears to be pushed super hard. I can also imagine some men not actually learning how to clean properly (because where would you learn that?), furthering the stereotype.

I think OP is just coming from a background of misunderstanding, rather than trolling. I guess they also didn't realise how charged a topic it would be.
