You're welcome to try "taking it back", but people haven't had such success with the rainbow. It's the same reason I don't wear neon colored rainbow clothes—because I'm not gay nor wish to promote that. How people want to act is up to them. But I'm suspicious of such penchants of certain iconography and I don't participate in them in my life. I certainly don't wish to give off a tell that says I'm one of them. I want to be set apart. And I also wouldn't want to make my children a target by letting them wear pizzas on their clothes. If anyone looks at them and knows what that means, than they are associating them with that in their minds, and who wants to invite that?
