This really is a battle that needs fighting right now. Transgenderism is one of the very hottest of the many fronts of the wars which Cultural Marxism is waging on Western Civilisation. It matters so much because it goes to the heart of one of the most important and contested issues which divide right and left: is there such a thing as truth?
*If you believe - as the Social Justice Warriors, liberal "intellectuals" and other relativistic cretins do - that truth is just a matter of opinion then clearly, you are whatever you say you are, be it a man, a woman, non-binary, polygender, intersex, trans and the rest of that nonsense list of LBGTetc terms.*
*If, on the other hand, you subscribe to the more traditional, rational view that biological sex (not "gender" - a left-wing invention) is determined by chromosomes and organs like wombs and penises, then it's pretty damned obvious that you're born either one thing or the other, regardless of how much surgical mutilation you undergo or how many hormones you take.*
*Crusading progressives want to portray this as a war between nice people who have feelings and horrid people who are stuck in the dark ages because of their vile prejudices. But it's not that at all. Ultimately, it's a battle over who gets to define what truth is: the rationalists or the idealistic fantasists.*
