Eh. Parades are fun and all; unless you are too immature and ignorant to see it as something more than it is. In that case, you are better off keeping it to yourself and leaving.
As Shook states, believe it or not, straight is the default in today's society. When you are asking a girl/boy out, you never ask if they are gay or lesbian or all of the above. You naturally assume they are straight unless they blatantly act otherwise. It's like saying you don't see people by their sk- off topic my bad.
It makes sense that people have a hard time accepting this as we live our lives molded in a way that usually does not promote such sexuality, from our parents to our religions. People say it's not natural. Ok then. I honestly don't care about such matters because, even if it's this and not that, it is becoming prominent in our lives, and just because you decide to close your eyes does not mean it will disappear. It's here, it's happening, deal with it (or don't).
As long as I don't have men knocking on my door asking for the D, I am fine. Also, good for you Shook for being confident enough in your identity that you are willing to share such info openly. This proves that you are more mature than most.
It's not like you're forced to be someone else . . .
