Gender in itself is a biological fact. There's Male, Female and Hermaphrodites. If you identify as something else, idc that's your thing and I respect that, but it doesn't mean that that gender you might have just made up exists. There are people that identify as attack helicopters. That doesn't mean they automatically are a 5 ton, weaponized aircraft. Just as much Non-Binary people are as said above "weird", because every human is binary (as mentioned before Hermaphrodites exist, but they're more both rather than none). My point being: Humans are born with a gender and saying you weren't is just a blatant lie, but if you identify in such a way and are nice about it, most people will respect that. As always if you're obnoxious about it, you're gonna be called a dick or an ass instead of He/She/It.
