I hate when my in laws come over

My in laws are coming because my husband's cousin is graduating and they're going to watch. They're staying for a week and I can't stand my husband's parents and he can't even stand his own parents. Whenever his parents are around he just hit boxes his car by smoking weed. My husband is high a majority of their stay usually and I'm at the point where I wanna get a little high too. His parents are just miserable people who only got married because his mom got pregnant. They argue all the time and have told my husband to his face that he was a mistake, he ruined their lives, they were supposed to get an abortion but his mom changed her mind and now she regrets that. His own mom has said he should be thankful that she didn't and said "Your welcome!" Because she wanted him to say thank you. They're just annoying drunks. Then my issues with my FIL is he's one of those people who constantly rant about communism. My daughter who is 6 had a playdate the last time they were here with a boy named Sergey. Which is a Russian name and he yells at me and my husband for an hour for letting his granddaughter be friends with a "commie". He threw his star bucks drinks at my husband that my husband bought him because my husband got a paper straw screaming about "these fucking liberals" won't even let him have a regular straw. He's hust awful. His mom just goes out of her way to insult and be awful. Like I get it. You had a kid and didn't want it and now you have to make everyone else miserable 🙄. I can't stand being around his parents because they suck the life out of you. My husband grew up with this being his whole childhood so he just smoked weed to get through.

Edit: Why they come around is complicated. My husband has this idea that eventually his family will come around and love him. He's holding on for them to realize he's worthy of their love.
