My father-in-law doesn't believe in evolution. He also believes in a ton of other crazy conspiracy theories. Now, every time he talks about something political, I make it clear his opinions are not welcome in this family and that until he can stop spreading disinformation he's sitting at the intellectual kids table. The evidence for evolution is overwhelming. If he can't get this basic scientific fact correct then he's almost certainly wrong about everything else. At best everything he argues should be held with a massive red flag. If you're scientifically illiterate you don't get to participate in society.
