My so makes fun of my family

I'm about to have my baby shower this weekend and my cousin is who chose to plan it. She chose to have it at a park now where i live the weather right now is horrible with rain. Anywho him and his family were steadily saying things like only white people do it at a park and oh I bet there going to have hot dogs and burgers and I'm not eating that shit yeah yeah yeah smh so I'm obviously white and he is Hispanic. Now he's inviting a bunch of his people right but they all want to bring bottles and beer.. my cousin who planned it has the park reservation under her name and wants the beer limited smh so now his family is like oh u know she's extra white is she scared about beer just always bringing up the "white" part and it's sort of pissing me off.. so every night lately my so keeps reminding me how how stupid it was to okay for it to be at the park because now it's going to be ruined and we should of done it the "Mexican" way his way supposably is his mom's house with tables chairs and bounce house and cook out which would of been fine but they wanted to do it when all my family was out of town and wasn't able to any later than the day they had chose.. plus i see all races do it at a park smh.. the main issues they are having is the beer but who's right here lol I feel like im in the middle and have to pick a side. It's just so horrible we're still texting about it and he says it's stupid to have games out there too that it's wasting time 😖😖 I m over it lol my anxiety is so high now. I feel like they just think they are better.
