Basic biology says there are genetically two sexes. Biology also says that there are instances when someone takes on the genetic profile of both a male and a female, hence intersex/non-binary. What biology doesn’t say, however, is how any one person can express themselves. If someone truthfully believes that the best way to express who they truly are is to say that they aren’t male or female, then it should be common courtesy to respect that. Even if you don’t agree with it, hate the sin love the sinner. And, as said above, in a hundred years it’s not going to f**king matter if someone else is a he she or they, all that will matter is right now if you choose to be a good person or not.
