AIO that my best friend hates the girl I like because shes a retired porn star?

My best friend(22M)and I(21M) are having the biggest fight weve ever had because of a girl (25F) I like. Ill call her Claire. Claire and I met recently this semester and shes one of the few people Ive really actually connected with. I think word got around we started getting close and people started sending me dms of X links during the time she use to do porn. She told me she did it for financial reasons. She use work 50 hours a week while juggling university and did it pay her medical bills. Someone posted a picture of me and her and a party and random strangers started dming me about her. My best friend, is really pissed because of it. Hes a christian more conservative guy so it makes sense but I feel like he was being almost mysoginistic and aggresive for no reason? Am I overreacting? I feel like hes not showing her any empathy. Am I being naive, and just getting too ahead of myself? Is he just looking out for me?
