Was I being over dramatic?

I'm 24 and my boyfriend is 34. I'm getting really tired of him and his immaturity. The other day we went to a donut shop and the young boy working had acne. When we left, my boyfriend brought up how disgusting the young boys face was and that he shouldn't be working and that his acne is gross and that the kid should be doing something about it. I got so mad at him and told him it's called puberty and a part of growing up and that I'm sure he had pimples growing up and he said he did but not that bad. He told me I was being over dramatic for being so offended by what he was saying. We got into an argument over it. Do you think I am being over dramatic? I just find him so immature. I couldn't believe what he was saying. I know it's kind of silly to be arguing over something like that but it really bothered me and in a way he was bullying and I'm so against that. I just want to know if people think I was in the wrong
