Why is height such a deal breaker?

I was scrolling tik tok earlier and saw some videos of short guys. One guy was attractive and fit, and he revealed he was 5'3 and the comments were very mean. Some girls were like "Oh." And others joked about short guys being cute in a passive aggressive manner. I don't get it. Nothing changed about the dude. He was still attractive, in shape, and had good fashion. He's the same man, why does his height have to be the deal breaker for these girls? I saw multiple videos in my algorithm like that too, it's very demoralizing.
