Well, you don't have to be a dick... kinda. in this day and age, you are seen as a dick if you do anything... ANYTHING a girl could possibly disagree with you with.

but you do have to censor yourself just because you are trying to get a girl. Even if she may hate you for it, always let your true self show. If a girl doesn't like it, too bad for her and move on to another one. plenty of girls out there. that will like you view on things.
