Most Helpful Guy
Maybe you don't like guys who SAY that you're beautiful, since often times it's just some hyperbolic fake way to garner your favour instead of a real compliment. And you know that those guys who easily say that you're beautiful are saying the same thing to a dozen dozen other girls out there at the same time and that it means nothing at all.

You think they are a threat, intimidating. You don't trust them. Understandable, but a guy who is infatuated with you will find you beautiful.
