I couldn't watch this whole thing, but it definitely made me rage a little.
At some point in the video, the dude "corrects" the woman when she says that being female isn't a costume. He says, "female isn't an identity. It's is a biological sex. 'Woman' IS an identity."
Most coherent models of gender vs sex will uphold this, but in heavily-trans spheres, you will get strung up for saying something like this. The idea that trans women on hormones are more female than male is now the prevailing thought among Twitter troons.
So, anybody participating in trans conversations is wrong at any given moment. Whether or not punishment is enforced is entirely up to the discretion of the authority figures in a space, usually mtfs.
This boy is being good and correctly calling out wrongspeak, so he gets a pass and is largely exempt from criticism from the trans community. (Additionally, he's supposedly not even a cis male, despite presenting as such and having the YouTube name 'Mr. Beard.' Somehow, I get the feeling the wouldn't get such generous treatment if he were female.)
Also, most of the pushback I see in the comments is about him saying that age-regression is cringe, even though he also validates all the bullshit about how it's a non-sexual coping mechanism that has NOTHING to do with being trans.
God, I hate this shit. When will it end..?
