I HATE my inlaws

Ta
Am 2 days PP, it was an arduous delivery, I'm still recovering in the hospital, and even though baby's name was decided 3 months ago, my fucking inlaws have the nerve to yet again bring up how they don't like baby's middle name. Out of respect for their culture, it was my idea that our only child have a Korean first name. Last name will be my husband's family name.
All I wanted was to have the middle name in honour of my adoptive parents, and the inlaws are still fighting me on this, even after baby is born?! I'm sitting here, fuming. They're super old people who believe that their culture and ways are the right way and only way (am always so tempted to say, if Korea is so awesome and everyone else so horrible, what are you still doing here?) and the only time it sets me off is when my husband spends time with them and comes back sounding exactly like them. As he did tonight when visiting baby & I at the hospital. I kicked him out as I was getting more angry with each word coming out of his mouth.
The inlaws are staying at our place until I'm discharged. I'm super hormonal and am very tempted to tell them off, and that they better be out of my house before I get home 😡
Oh, at our wedding, my inlaws didn't want my parents names on the invites bc they're my adoptive parents = not real ones. Yes, the invites I paid for, the wedding my fake parents helped pay for while you contributed neither time nor money. I very diplomatically told them to fuck off then and it looks as though I need to remind them who their daughter-in-law is as a potential adversary.
