Yeah, sign language is speech. This act most certainly would not fall under that.

It really doesn't matter that the sign said what it said. She was just standing there holding it. It's not the speech we agree with that needs to be protected, it's the speech we don't. She is a good example of American values by attempting to exercise her right to freedom of speech however it's been infringed in front of everyone.

He should apologize to her and instead of getting physical with her "present a better idea" or whatever we say. What that looks like is a man bullying a woman colleague and theft. I highly doubt if it had been a man holding that sign he'd have snatched it like that. The optics for this are terrible. Additionally, when he tossed it in the air as it came down it almost hit President Trump. Imagine how that would've looked.

Lastly, they use the same logic to justify these same types of actions and we rightly call foul. Now "our side" is doing it, that's a great example to set!
