What do you expect to gain in doing this?? They don’t need to be told this, and telling them this is bullying. Are you actually trying to hurt them emotionally?? Because telling them this is just cruel. You’re obviously a lot taller than those you’re telling this to, and telling shorter men/guys that they “won’t have a chance” with the opposite sex all over their height is just despicable
That is very far from a fix. Fighting negativity with negativity doesn’t male you the winner here.
Be secure in who you are. Know your value comes from a world of other factors and height is only one minor aspect of your physical appearance. It is unfortunate that the ignorance of society has consequences for you, but your best revenge is to live well.
I mean, it can absolutely work as a comeback, but it definitely shouldn’t be a default response.
Yes, reading the room is still required, and then maybe explaining the comeback afterwards because usually if they’re dumb enough to just blurt out that sort of thing they’ll need it.
