That sounds exactly like how they spoke about jews before hitler came to power 😬 I also have a semi-racist dad, it really gets annoying, but I usually just tell him I don't wanna hear about it and he shuts up about it eventually. Last time he tried talking about it we sat in the car and I was trying to strike up conversation about politics because I know he likes politics, and I was a bit interested in Trump becoming the president. He of course turned it into talking about immigrants and I was like "I'm trying to have a fun conversation that we both enjoy, and you know I don't enjoy you talking about that shit with me."
