My brother's favorite color when he was little was pink. All of the kids in his class made fun of him for it and now he hates pink. My mother was not amused but his teacher wouldn't do anything because "boys will be boys".
When I was in highschool pink shirts were really in for boys. And whenever a guy asked "isn't that really gay though" all the 'gangsta' kids would be chuckling in the back saying "hey man...you ain't know nothing now let the man wearing his fucking shirt" and you'd automatically be that uncool guy who's cramping everyone's mad swag.
Basically, even teenagers probably don't give a fuck, and those are the most judgmental people on the face of the earth. If you are more prejudice than a teenager, something is fucking wrong with you. These people ostracize other people for not shopping at GAP.
Someone needs to point out to these people that the whole color coding of gender is arbitrary. In fact, it was originally the other way around. Pink was considered masculine, and light blue was considered feminine.
