"Extended,,, pink is for girls. Pink is sissy. Dresses are sissy. Girls are sissy " etc has not that much to do with the actual color pink, but OP's projection

"Extended,,, pink is for girls. Pink is sissy. Dresses are sissy. Girls are sissy " etc has not that much to do with the actual color pink, but OP's projection of what it implies. Not everyone has this rather lengthy and extended negative association with pink or a generic female shape being dressed in a skirt. So I'd say this has more to do with OP's attitude rather than the icon. Distinctions have to be made somehow, otherwise we'd have two identical icons. As for making them letters, well, the point behind universal signs was for people who are not native English speakers.
