I have a hard time understanding why people are upset over peaceful protest. For so many years, when people of color protest, they are told to do so peacefully. And now, when they do it peacefully, they're told by the POTUS that they should be fired from their jobs, and they're called sons of bitches.
Even if I didn't agree with the message of their protest, I'd be perfectly fine with it. It's their damned rights to kneel if they want. I'm pretty staunchly anti organized religion on a large scale, but I'm not flipping out and calling for heads every time a player prays, does a cross or whatever. Let people practice their beliefs, protest, speak, whatever, as long as it's not hateful and/or an active threat towards someone.
