Candy, I agree David should post a summary of what he is linking to. Instead he just offers a headline and a link to some random person's post on Facebook.
I have actually watched a few of these and it is clear when you ask David about them or point out the actual video is contradictory to his claim he hasn't watched them. He just takes someone's inflammatory headline or text around the post as a truthful summary of what he is asking us to watch. In other words, he can't answer those basic context questions you asked because he hasn't watched the video himself.
