How to address my friend about some offensive statements?

I’ll try to keep this concise guys!

My lovely boyfriend is short. A good four inches shorter than me. Le gasp! I really don’t care, I just don’t wear heels as often – but the question isn’t about that.

So I was at my best friend’s place and we were hanging with her boyfriend (also my good friend) and a few other people. The conversation was about males that approach us. Somehow, a tangent started from my friend as well as another female guest about how short men are inferior, that they question their manhood, and that they basically laugh and think they’re above them. Kind of like “lol what makes you think you can talk to ME”.

Everyone laughed and basically moved on, but that really bothered me. I don’t see how she didn’t even think to be tactful or anything about what she was saying when it basically came off as “your boyfriend is inferior because he lacks inches in vertical height ”. Its elitist and offensive to me and kinda insensitive to my relationship.

If she was a random person I wouldn’t care but since she is a close friend I feel a little more bothered by it. I know she probably wasn’t thinking much about it, so how do I even talk about it?
