Feel like my dad is becoming racist

My dad is a white man, I’m a mixed girl who’s half black half white. When I was younger I never heard my dad say anything racial but as I got older into my teens I noticed some weird things he would say. Such as:

*He referred to our middle eastern neighbors as terrorists and got angry at me because I said that wasn’t okay to say.

*When I bring up slavery he always feels the need to bring up that Irish were also enslaved (my dad has Irish ancestry and is very proud of it)

*My sister recently told him that Harriet Tubman is going to be on the $20 bill (which I’m not even sure is accurate because they have been talking about that for years now) and he got mad that they’re removing Andrew Jackson even though he was responsible for the Trail of Tears which harmed Natives.

*Says Trump can’t be racist because Kanye West supports him

*Says racism in the United States isn’t that bad compared to other countries even though he’s never been to other countries so how would he even know that.

*Says the United States can’t be racist because they elected Obama as president.

It makes me feel uncomfortable because he never used to be like this but as he became older he started acting different and I worry one day he’s going to end up being racist towards my sister and I. I bring up that the stuff he says is inappropriate and he doesn’t think he’s racist.

BTW this isn’t supposed to be a political so please don’t take it like that, I’m just sharing some odd things my dad has said and I’m not sure how to handle it.
