A question about rejecting women?

I just want peoples opinion on this. The reason I ignore and reject women is because I'm not interested in a relationship, nor am I interest in one night stands. But I notice that if you ignore and reject good looking women they will often start checking you out. But many of these women love having the power at turning men down, so why do many women get annoyed if I do the same? When I was 21 I worked as a bouncer at pubs and clubs. I would ignore and reject women no matter how beautiful they were. I refused to give them attention to boast their ego. But why is it that many women pretend that it doesn't bother them? Of course it bothers women when they are turned down or ignored by a man that they are interested in. Why are women so proud that they hate to admit this? When I rejected women when I worked as a bouncer some of them would show their frustration and spit their dummy out. And it's natural to get upset by being rejected by someone your interested in. Why do women like to show that they couldn't care less? Why such a proud attitude?
