Right wingers are very successful at getting their nonsense into The Discourse daily in part because plenty of journalists either basically agree with them or believe they have to cater to an audience who does.
But they also are successful because so much of their nonsense is nonsense, and it lets liberals talk about how stupid it is.
I don't have a solution to the problem, but I do try to resist the lure of the freak show more than I used to.
