AITA for thinking my dad and step mom are disgusting for not inviting my sisters husbands to the wedding?

So my sister is getting married to the love of her life. My parents are paying for pretty much everything for them (the wedding is on her 30th birthday and they have been together for almost 10 years) and they wanted to pay for something special.. So my dad thought it would be good to hire a few sexy girls to go topless for a portion of the reception where there are no children. He didn’t want to tell my sister because he considers it a surprise. My step mother and him both have several siblings and spouses of siblings who aren’t bringing their spouses to the wedding. <br><br>My dad told one of my cousins and it go back to my sister and her fiancé. They are very religious and do not approve of their wedding being sexualized like that. She begged them not to and my dad told her fiancé that it was his wedding too and he also got to have a say. My sister came to me and asked me if I thought she was wrong.. I told her I personally wouldn’t want that at my wedding and I think she has every right to determine how she gets married since it’s her and her husbands life. <br><br>My sister told their parents that her fiancé doesn’t want any of that stuff there and my dad said he’s not going to listen to someone who isn’t in the family. Then my sister and her fiancé got mad and told them the guys aren’t coming if they hire those girls.. I guess my stepsister is married to a guy that works at a strip club and my dad was going to hire some of the girls from there. <br><br>Aita<br>Edit: To answer a few questions- Yes.. This is her wedding and she doesn’t want anything inappropriate. The guy her stepsister is married to is one of the groomsmen and the strip club girls would be there where the kids are. They did say if we hide them from the kids they aren’t ok.. But people got mad because the guys aren’t coming to the wedding. They were never invited.. I also want to say there is no drug use or anything like that as it is in a church hall.
