Most of my wine drinking friends in Cincy were quite liberal. One lady came to me earnestly asking me to talk to her about "assault rifles", she was writing a letter to our congressman. I explained the facts to her, and she nodded, and later showed me her letter, I sighed. Nothing I had said sunk in, at all. I just nodded.
People are SO invested in their beliefs that facts rarely have any impact. She COULD have written a letter that was factual and asking for "common sense gun control", but she didn't, not that a perfect letter would have mattered. She's not a dumb person, but either didn't believe what I told her, or thought I was making it up. Everything I said was completely factual. It just doesn't matter.
