I don't know a single female who doesn't get it (I see some online, but my friends IRL get it.)
I wouldn't say I have friends who don't get it, or say that I don't get it, but I did have a cascade of thoughts about it as I processed the meme. Mostly because my ventures into anti-racism, greatly influenced by my partner, has affected the way that I see the world. That's a good thing, I think.
So it wasn't that they, or I, didn't immediately get it, but it kind of encompassed an ongoing problem with feminism, I suppose. How it centres the gender conflict between cis people. Cis white people especially.
Basically, the fear that leads many women to say the bear, also leads many white people to overreact to the presence and even go as far as resent the existence of Black people. So even as I wanted to defend the women saying "bear", I was aware that in real life, that plays out as a white woman cowering in fear because a black man is in her vicinity. That fear has unduly cost lives.
I became more uncomfortable when some people suggested that men should call out other men if they are unhappy that women should choose the bear. Not unhappy about the suggestion that men police other men, but the suggestion that black men should police the actions of white men (a big danger to them) so that women feel safer and won't react with that fear to them.
It misses the fact that the men that white women fear the most and date relatively infrequently are most harmed by their fear of men are black men. The men who harm them the most are their most favoured intimate partners: cis white men.
I get that some people are trying to distinguish these issues but I don't think you can. Racism is at least as equally harmful to humans as sexism and often linked.
