First off, they weren’t expressing “romantic interest”. They were expressing the desire to have sex with me which is insulting as hell to anyone that believes considers sex only for a marriage relationship and a marriage is only possible for me with someone of my own culture and ethnicity. I’ve always been open about that (i.e., it usually comes up in conversation immediately when people ask about dating or family relationship). I wasn’t married in college, but I wore a wedding ring and used Mrs. for introductions in order to avoid men trying to flirt with me. If some guy can’t read those signs that I wasn’t to be bothered with, or let’s be realistic, choose to ignore them in order to suggest I engage in an immoral act, I’ll use whatever tools are available to get rid of him. And I am not light skinned enough to qualify as white.
