That is so true. Overweight people, women who are hairy, very tall people of either sex, very small people too. 'Matter out of place' will always be seen.
But with trans, a lot of it must be our paranoia - it could genuinely be someone thinking ''that's a nice jacket''.
I know that I have always looked at people, because I find them fascinating. I love sitting behind sunglasses and properly examining someone - mine are so dark that if I turn my face slightly away, it looks much less obvious.
I can't think I'll ever not.
