Reading the OP, 2 idiots could harass anyone, for any excuse, whether: race, religion, sex, disability, age, dress, or simply being a ginger, from what I read.
Everyone may and can get harassed. Most times, a bus, train, plane, carriage full of people don't want to get involved. Not knowing if the harassers are nutters or armed.
Guess trans are the flavor of the week, month, year, decade.
Please, we need another reminder how different and included you should be.
Is there anyone, ever, that didn't get harassed one time or another. We got harassed for having long hair, living on the other side of the tracks (literally), and being poor.
And associating with black folks ... 'damn negro lovers' ????
Cry me a river....????
