Thanks for adding that point. In the case of the particular store in my example, I’ve seen the staff there be far more civil to trans women (in feminine clothes) than they were to me. But that may be because they believed they would be in trouble if they weren’t. With me, they probably thought they could get away with openly displaying their prejudices.
And another point worth considering: Some ‘genderqueer’ people dress as men during the working week, but as women at other times. What if one such person, whilst wearing ‘male’ clothing, wants to go into a store after work and pick out a dress to wear at the weekend? In such circumstances, they may get treated to almost exactly the same prejudices and discrimination as were directed at me.
And thanks for your very kind words of support! :)
