There ARE actual real life groups fighting about it. There have been for AT LEAST a few years. Go to any protest where women's rights could be a subject - feminism, lesbian/dyke marches, Pride, sex-segregated safe spaces, etc - and there will be aggression and violence towards supporters. The aggression and violence does not stop until support ends and identity-inclusion begins.

And the worst part is the people who are claiming that the aggression and violence are just from fringe groups are essentially gaslighting and directly contributing to the problem!
