Jake, you fucking tool.
Your own ideology states that if someone claims to be a gender, they are, no proof required or evidence needed. You cannot then turn around and tell them they're not without being massive hypocrites. When the inevitable happens, and first shitposters, then normies start claiming to be trans on Social Media just to get you banned for being transphobes (an easy thing to assume, because they were and still are better than you at this whole "internet" thing), you will be strung up by your own idiocy, and we will fucking laugh at you.
