I'm going to put a height preference in my dating app bio.
Is there a reason why you're going to do that?
It's because I don't want to date anyone shorter than me.
It's completely fine to have a height preference when it comes to dating, so it's reasonable to put that in your dating app bio, as long as you aren't rude about it.
I think being rude about this will get more attention.
Being rude to potential dating partners seems like a negative way to go about the business. There's nothing wrong with wanting to date people taller than you, but insulting people shorter will only make you seem purposely rude.
