How to deal with racist in laws?

I guess this falls under lifestyle since it is their “lifestyle.” Anyways with the BLM movement and protests I have come to see how blatantly racist and ignorant my in laws are. Mostly my fil. Don’t get me wrong I absolutely love them both to death but this is bothering me. Anytime we see something on tv they’re all like “well blacks kill more white. Blacks kill more blacks than white people do. Anyone that’s rioting is a pos and they don’t deserve any respect, blah blah blah.” It pisses me off. First of all, they can’t even have the decency to maybe say person of color or African American. Just “blacks” my mil grew up in South Africa. My fil is a freaking country hill billy so it makes sense he thinks this way as all the country folks up here do. I try correcting them with actual facts but they just argue. They think the people protesting peacefully deserve to be beaten and assaulted by police. They whole heartedly believe poc are more racist to white people for some reason. I just can’t anymore. I can’t argue and I can’t respect their opinions on this. It’s complete shit. It makes me look at them differently of course. He shares the most stupid shit on Facebook. I’m just so done. How can I get them to see they’re part of this problem? How can I make them understand these thoughts are racist? My husband literally has South African in him!!! He’s light skin (fil is his step dad since he was 3) I’m native and their thoughts on indigenous racism as well are tainted and wrong but way more understanding. I don’t feel safe personally for my husband or myself if this is how they actually feel towards poc. So what can I do? What can I say? I’m really struggling here because I love them but it’s so hard to just shut up about this. I understand everyone can have their own opinions but not when you’re being openly racist. That’s not okay.

This is his recent share. Like are you actually comparing the kkk to fucking blm?????? I want to punch whoever makes this stupid shit.
