Back in the late 80s, a friend of mine went on Wheel Of Fortune, and won pretty big. Back then, you won "money," which you then spent at the end of the show in the big showcase of products.
My friend went with a strategy, and bought stuff like wall-to-wall carpeting and a fridge, but also a couple things like a gaudy gold watch.
When he got home, he was getting his haircut, and his barber said "I saw you on Wheel. That was a nice watch you got." My friend sold it to him. That was his strategy - buy stuff for the house, but also buy some stuff that would be easy to sell, so he could pay the taxes out of his winnings.
First you get people comfortable with defending genocide in another country, then they won't be so resistant when you start doing it in your own country.
