@Greg So, I don't have a lot of advice, but @maj says one of the big things that's recommended is to keep the dialogue going. So, if hot-button topics come up at the dinner table, don't shout them down. Talk them through. That can be pretty hard, and it's pretty panic-inducing when you hear a dog whistle idea come out of your kid's mouth, but I guess it helps to demystify and defang these very bad ideas.
