My plans for this evening went up in flames

It's not exactly a big deal or anything, I was probably just going to spend the evening practicing my coding but either way I'm upset that my evening got ruined. Why? You ask.

Well we have guests coming over which isn't bad or anything but it's just these specific guests, my mom's friend who also isn't bad or anything but rather her son is really annoying. So she's coming over with her son this evening. I'm really not in the mood to deal with his shit. Like he's actually the most annoying person I've ever met and recently he's discovered dark humor (racism, homophobia, transphobia). He's out here saying racist and homophobic shit thinking he's funny, me and my sister say that it's not funny but he doesn't listen, and like some of his jokes make my sister uncomfortable but no matter how many times I tell him to stop he just keeps going. I remember one time we went to a restaurant and he was spewing ableist shit and I was so embarrassed, Waitress heard and everytime she came to our table I went to the bathroom because I didn't want her to think I was sitting with him.

That aside he's also very sexist which is very bad in itself but when his sexism is directed at my sister, I have never wanted sock someone in the face more than that. I just hope he will grow out of this phase at some point, like could he watch a contrapoints video or something please. Anyway his mom doesn't say anything about his comments and my mom doesn't either, so then it's my responsibility to teach this guy political correctness. 

But why give this guy the time of day then? Well my mom practically forced the friendship, she said That he had no friends and that I should be like an older brother figure to him and I've been in a similar situation so I stuck with him and now look where I am. Maybe I'm in the wrong here, I don't know, we just don't hit it off and I really hate it when he comes over, he always had to wreck my room and break my shit, like I love limp bizkit but you don't need to break stuff. 

On a more positive note, I'm 17 and in a year I won't have to deal with this because I'll have a job and responsibilities to deal with instead and that's a trade off that I'll happily accept. He's been talking more to my sister than he has to me recently. Probably because he tries to shock me with his humor but I've heard far worse things in my Seventeen years on this earth especially being outed in the 6th grade and having various slurs and insults that he could not fathom be thrown at me constantly. Besides when I'm 18 I can make my own decisions and I'm not gonna let my mom tell me that I have to be friends with someone.

That probably came off a little harsh, I also wanna put it out there that I wouldn't sock him because I have little twink arms and I was exaggerating at some points because I got swept up in my writing. Thanks for reading, do you guys know how to deal with someone like this, do you guys have anyone like this in your lives
