It's the bigotry and hate that needs to be the focus of any action, not the act of protesting. I disagree that it would be detrimental for kids to see people exercising their freedom of expression, as thorny as the issue is, ultimately if you're getting kids thinking critically about the world around them and their part in it, that's a very good thing. But these bigots are literally protesting the existence of queer kids, they are protesting to be hateful and nothing more. That shit is not okay.
