I think men under 6' are subhuman and should not be allowed to reproduce
Why do you feel that way about men under 6'?
I just think they're short and shouldn't pass that gene on.
You do realize people can't control their height, right? You sound sexist, and that's wrong.
I don't think it's sexist to have preferences.
It's fine to have physical preferences, but saying that a whole group of people is less than human for something as trivial as their height is just mean. You should try being more accepting of people.
