Good point. How about this: why are you in favor of Mac Donald saying everything she wanted to, but against protestors saying all they want to? You are selectively arguing in favor of some people's speech, and arguing that others (the protestors) shouldn't have expressed themselves, and then accusing me of selectively allowing the protestors and not Mac Donald. I'm cool with Mac Donald having said all she said, even though I (at least mostly) disagree with her. I'm also fine with protestors booing her. How am I being more selective than you?
> Your best argument is a ridiculous straw man?
That in and of itself is a strawman argument. My comment clearly pointed out that it's unfair to shut up everyone in the audience and only allow one person to speak, but you're looking at it in its weakest form. Meanwhile, I took what I felt like was the strongest part of your argument, and showed why I thought it was flawed. How "embarrassing"
