I had one friend whom I worked with where we had a some great discussions, but after one talk on Facebook about Gates' Ted Talk, I saw him make a separate post saying, "You can tell when someone doesn't do their research." I wanted to say ditto or something lol but I left it at what it was. That was over a year ago. I just saw him today post the meme where one guy is covered in propaganda saying, "they brainwashed you" and and the other is holding an American flag saying, "really?" I thought that was a nice clue he's coming around.
