Are Shy Men Capable of Being "Real" Men?

Yesterday I got into a discussion with my sister and her boyfriend. I have liked a shy guy for some time now and they said that they don't think he is for me because since he can't come up and say hi (he stares a lot) then he would not be capable of handling real life situations or he would let me run all over him in a relationship. I totally disagree with both of them and I told them so. Shy guys (and guys in general) do you agree with me or my sis and her boyfriend?
