I agree with the write up more or less. I mean it's not a big thing, I think there are plenty of rainbows out there where people don't necessarily automatically think "gay pride symbol", although it is pretty strange when I hear someone say "it's a gay message because rainbow" and I'm thinking "What? No, it's just a rainbow."
But yeah, to be the first one to come out and say that it's unfortunate that you can't have a funny rainbow shirt without people thinking it's a gay thing, heck no. I know the crapstorm that kind of thing brings down and it's not worth it. You're a braver man than I, Woot.
I mean, it's totally fine for the gay pride folks to use the rainbow colors as their thing, no problem with that. Just, people out there, have an appreciation for context. Even the Swastika was a preexisting symbol, it's just that people stopped using it for other things after WWII (I'm not equating gays with the WWII bad guys, geez, it's an analogy). People still use rainbows for other things because they are pretty and because it's not even a manmade creation, it's the bloody natural light spectrum for pity's sake.
