Have you come to the same conclusion for parenthood? Are adopted children not real, and we must not refer to their adoptive parents as "parents"? You understand why that is hateful, right?
Biology may be a fact, but we can, and do, choose to value the link between parent and child socially as the most important part, not the biological link.
We can do the same with gender, referencing identity over biology in the general case. Why have you come to the opposite conclusion?
