There are a lot of good points in this post.
Fame lets people avoid social repercussions, but that doesn’t mean those repercussions don’t exist for ordinary people
Caitlyn Jenner can be as visibly and fabulously transgender as she wants, because being transgender is a big part of her job. She’s organized a lot of her life around being a transgender person. Any friends she was going to lose for being transgender have already been written off as losses. Anybody who wants to harm her for being transgender is going to get stopped by her bodyguards or kept out of her giant gated mansion. When she argues that transgender people face a lot of stigma, fear, and discrimination, she mostly isn’t talking about herself. She’s talking about every transgender person who isn’t Caitlyn Jenner.
Likewise, Sam Harris is pretty invincible. As a professional edgelord, he is not going to lose his job for being edgy. Whatever friends he’s going to lose for being Sam Harris, he’s already written off as losses. I assume he has some kind of security or at least chooses not to live in Berkeley. So when he’s talking about his ideas being taboo, he means taboo for everybody who isn’t Sam Harris. . . .
