You're a man. We men can think this way.
Women cannot think that way. In their minds, they cannot separate a man's sexual value from his value as a human being. This is why, for example, it's virtually impossible for an unattractive man to get hired for a job if the interviewer is a woman (I've had several jobs in my life and all the people who hired me were men). Women treat job interviews as if they were dating interviews.
So many times in my life, I've received poor treatment from women - job interviewers, waitresses, nurses, air hostesses, etc. - because even though the situations in which we were interacting weren't sexual at all, those women couldn't help thinking that they somehow had to judge me as if they were sexual situations. They felt the need to symbolically "reject" me by providing poor service/discrimination.
