Are All Guys Like This ?

So I was wondering if all guys are like this ?
So I was walking down the hall one day last year.When a guy asks me out ,I said nothing and walked away he started laughing .Then he turned to me and said that no one would want to go out with a suicdal ,cutting B!**h ,that listens to screamo.Now at this time i am was used to guys doing this to me .Just because i am not allowed to date yet.But this made me wonder if all guys were like this .But what they don't understand is that i am different because of my past expriences.They do not even like that i am different

So I have One question are guys like that? and why are they?
