Once again tapping the sign: “You live in a bubble,” was only ever an explanation for the surprise of 2016, and should never be extended to, “and maybe, the guy who thinks the NAZIs winning would be good, is right.” Or the other examples in this thread.
It's easy to say we should be having these conversations if you don't have to engage with the reality of what these people believe, or the implications in your day-to-day life. I don't need to debate World War II with the guy who thinks the world would be better if the Nazis won; real guy I know!
