Ugh - that’s fucking gross of people, and I’m sorry to hear that.
My argument was more when considering ‘most people’ - most people is a lot of people. An individual doesn’t really interact with most people. But that said, you can certainly interact with ‘enough people’ that an expectation of shoddy treatment is pretty reasonable (if a pretty bullshit set of circumstances individuals shouldn’t have to suffer).
Pedantry on my part, I guess, along with likely blindspots I have as a cis male. Fuck transphobes…such meaninglessly hurtful bullshit.
