It sounds like your friend let the groomers in the kid's school indoctrinate her child. As a parent she's supposed to be protecting her kid, not letting him be led into the deviant, twisted BS these beasts try to pass off as "tolerance".
Too many parents nowadays want to be their child's friend and not their parent. It takes more work to be an actual parent, to say "No." and to work with the kid to make them understand. Just a shame. Their kid suffers while they just thrash around looking for sympathy and gleaning virtue-signaling points from equally weak-minded friends. You're not one of those - tell her she's damaging her child. Here's a suggestion - if you see the two of them, ask the kid, infront of your friend, if his teachers at school told him it was okay to dress like a girl. Maybe he saw Will Smith's son do it or one of the other sick pedowood children.
Since you have nothing in common with her, if she ends the friendship, so be it. I recently told a long-time friend that I am not about to call a tranny we knew from many years ago "She", that he's got mental illness and that it does nobody any good - least of all the poor soul (who is likely reacting to trauma) - to be pretending along with him. If my friend wants to end our friendship because I won't participate in the degradation of this individual, so be it.
