Yeah, the majority of stereotypes are accurate in a statistical sense - that’s why they exist. But it’s impossible to make any general statement on this board (eg “men are taller than women”) without nitpickers demanding you add a bunch of caveats (….but obviously there is a big overlap, there are tall women and short men, we shouldn’t assume anything about any individual…) that everyone knows anyway. It gets old.
Every time I’ve been asked to give an example of something contentious, and complied, it immediately derailed the conversation into discussing the merits of the individual example, rather than the general principle. Plus on less moderated forums, got me nasty accusations (thus immediately proving my point).
Anyway, IMHO the answer to the OP is that you can’t, because the people shutting you down are generally not acting in good faith, but would prefer that nugget of truth not be discussed and are using the existence of the noxious stereotype to prevent it. It’s irrelevant how you phrase your point: their objection is to it being made at all.
