I just watched it. There weren't immigrants. They looked like the anti war liberal crowd.
This makes me ill. They know the "loopholes" of "freedom of expression". I bet their kids can pray in school, but mine can't. Wake up America.
I think you are very mistaken. Are you suggesting that Muslims do not look like what you imagine them to be? I know Muslims who do not look like Muslims too. How I know them? I know them because I was a Muslim myself until recently.
They're Muslims, not the typical anti-American liberal crowd you described. They were chanting in Arabic, and a few were wearing Islamic garb. There may have been a few sympathetic liberals watching, but the desecrators themselves were Islamists.
