Brandon, your mother is correct. Being black is dangerous, but being a black male is the most dangerous.
One black transmale said that police suddenly became hostile to her the moment she started presenting as male. One white transmale said that suddenly mothers were hiding their children if he forgot he was presenting as male and smiled at a baby.
White people who say that if you obey the rules you'll be OK are only speaking from their white privilege bubble.
Even looking "ethnic" can get you in trouble, and I constantly read about black people who are shot for simply being black, with police body cams now showing them planting drugs and guns on their victims.
My nephew, who has dark hair and Latino features was pulled over for "speeding" while driving in the south and accused and harassed by the officer. My nephew is an upper class concert pianist, but it didn't matter.
But it does no good to tell white people that..they are blind to their privilege and usually only become defensive and angry.
But if you can't find a black therapist, that can't be helped, unless maybe you can do a google search to find someone and are willing to travel.
My ex-husband is white, 6' 1", handsome, fit, from a wealthy background, an ex-Navy and airline pilot, and the revered oldest son in his Republican family, yet last year he casually told me he was going to transition to present as nonbinary female. He had never even hinted at such tendencies when we were together, even when I asked him directly.
He was off-hand and casual about it, talking like all there is to being female is learning to apply make up and buying cool clothing. None of my warnings have made the slightest impression on him, but I guess he'll find out for himself what will happen to his life of white male privilege. He'll still be tall, fit, and white, but my guess is he'll get a dim welcome from his relatives and current wife.
But I can't tell him anything. He thinks it's all fun and games, because up until now, everyone has honored him.
