Dont believe in COVID-19.

My father in law doesn’t believe that this virus is real. Yes, he is those Republicans that believe he is being oppressed because he has to wear a mask out. I have never supported those beliefs and I don’t want to talk about politics bc it’ll just create tension. Anyway, yesterday he was almost bragging how he DOESNT wear a mask or protect himself and that people who wear them are brainwashed bc COVID-19 is nothing but a “cold”. His whole family doesn’t protect themselves! And I am not comfortable going over anymore. We have a baby now and I don’t care what they think but I am not letting these people increase my child’s and my risk to getting it. I just don’t know how to go about it. I told my SO to talk to them and we’ll see how that goes but do any of y’all have family members like this? How did you go about it?
