Why?

*Note* I'm not trying to make this seem sexist. I've just been thinking about these questions for awhile.*

Dear world,

Why is it okay for a girl to dress like a boy, but it's stupid for a boy to dress like a girl?

Why is it okay for a girl to like any color, but it's "gay" for a boy to like pink?

Why is it hot if a girl is a lesbian, but disgusting if a guy is gay?

Why can't a girl play football? (Maybe there could be a girl's football or something.)

Why can't a guy be a cheerleader?

Why is it embarrassing to tell your mother you love her in front of your friends? (I know everyone is not like that.)

Why are girls who have sex before marraige considered easy/sluts, but a guy is only considered a pervert or gets cheered?

*If you send me your opinions, I promise I won't judge them. I am going to post this to another website later just to get more opinions.
