Nope, not hard at all.
People aren't "assigned" anything at birth. You're born the way you are. Your sex is recognized or acknowledged at birth.
Attempting to redefine the word "assigned" relative to a person's sex is just one more example of the left attempting to re-define well understood words to further their political agendas.
Not falling for that crap has zero bearing on whether a person supports lgbtq rights. This has nothing to do with lgbtq rights.
Identifying as something does not make it so. One could identify as a potted plant, an Amazon, a Pygmy, or an empty bowl, but that doesn't make them any of those things.
Not hard at all.
