I don't get it.  How did the President place his hand on the Bible & swear to defend the Constitution of the United States of America without having read it.   Freedom of Speech.  It's right there.  Do I think this is the best way to protest?  Actually, no. I think that there are much better ways such as galvanizing the vote at the local level all across the nation to put in power people who will fight to protect us all.  Mayors, you know, hire police chiefs.  If a Mayor hires a racist police chief, then oust the Chief and the Mayor.  And galvanize the vote so that we never again have someone who cannot figure out that his comments matter, & he's upending the world with them even though he had no clear mandate from the people to do anything & didn't even win the popular vote, and enjoyed exaggerated loyalty from Russian Trollbots.  If everyone who really cares about this country voted & worked to serve the public good, we wouldn't need to take a knee, we could stand with pride.
