Is it toxic to be rude to people that take an interest in you?

For context, Im very rude to women who flirt with me or like me, because I know my worth and I’m realistic… who would genuinely be interested in me? Like that’s so unheard of. And, if I have a preconceived notion about you, I’m not going to want to date you. Like if you seem mean, I’m gonna want nothing to do with you. This girl who was interested in me asked if I liked girls, I said no and was very rude. I just can’t fathom someone liking me.
