AITA for not letting my sister and her family stay at my house while they’re in town?

I have a sister who is 3 years older than me. We are both girls and had pretty ok relationship until we were kids. After that, not so much. I could say she’s the complete opposite of me when it comes to personality and values. We always argued and fought as kids. I once caught her wearing my clothes to Prom, it was my only dress and she refused to leave until our parents made me let her wear it and I had to stay home. She also opened my university acceptance letter and read it out loud to a party full of her friends as a joke. She then went on to steal a crush of mine in high school. I was so upset, we haven’t been close after that. <br><br>When it comes to politics, religion, morals, everything I’m left and she’s right. I’m an atheist and she goes to church every Sunday.<br><br>Before I moved to the city for college, my parents would always make me go to her house and celebrate holidays with her husband and his family as well. I was so uncomfortable around them. Her husband would always make fun of how I looked and his family would make fun of my hobbies. The husband’s mother would make jokes about my weight, she would say that I get fat very easily.<br><br>I would complain to our parents and they wouldn’t do anything and just make me go anyway. They even made me spend the night once when she and her husband went out drinking. I was so annoyed and I’m 99% sure his uncle tried to sneak up to my room while I was sleeping but I locked the door and nothing happened.<br><br>I left as soon as I could and moved to the city for university. I only came back once or twice to see our parents in the 10 years I’ve been away and I never stayed at her place. My sister didn’t make an effort to see me either so it was all good.<br><br>I recently bought my first house and our parents found out. They called me and told me how proud they were and my sister asked if she and her husband and kids could stay there for free when they visit in Spring break since I have an extra bedroom. My answer was hell no and my sister got mad.<br><br>My parents said that I’m being rude and immature for not letting them stay with me for a week. I told them that I’m not comfortable and that we’re not close anymore and I don’t want to host her racist and bigoted family under my roof. I don’t want her kids to hear me cussing or catch them listening to my vinyl records that have swears on them. I’m gay and I don’t want to hide it when they’re around. My sister got mad and said that I’m the immature one that I need to grow up and be an adult.<br><br>So AITA?
