Sorry about that. I have uncles of the sort and a lifetime of experience getting through family gatherings with them. You should go into the standard uncle encounter like you are going to speak to a young child. His opinions on immigration will be as loudly expressed and as relevant as a child raving about Fortnite and if you manage to get any point across to him you should feel the same amount of pride. Just don’t miss out on meeting any lovely part of the family because of unclephobia. I have aunts and cousins who make it worth listening to hours of uncle talk if I have to to meet them. I hope everyone else is so lucky.
