Re: the expert on TV, I've noticed that pattern too. One example I noticed was when they had a vaccine "debate" on TV. They had a doctor who was pro vaccination, and then when it came time to hear the opposite side there was a battling single mum with her kids. They asked her why she decided not to vaccinate. She said "Well... people have their opinions and ah... it's a personal choice."

I like to post little propaganda tips like that on Facebook sometimes to try to prime people's minds, so they know that when a pattern like that comes up, it's actually a classic trick. It does make you wonder how people avoid being scammed when so many fall for these really basic tricks.
