I need help arguing a generalization about women

I never thought I'd be here, but hell...

I just had a fight with my best friend (34M). He insists not just many, but most women will disregard a man because he's not tall enough. Please, how do I explain that his personal experience (and his back up is "I've seen it happen online 🙄) doesn't make the rule, and that he's generalizing? I know some women are like that, but not all, and definitely not most. Is there any...idk study done on it, or polls taken, or anything concrete I can use? I'm heartsick to be in this fight with him.

Edit: I'm heading to bed. Thank you, everyone, for your insights. I think my friend and I have ironed things out. I really appreciate you all. ❤️
