Yep. Someone's about to *expletive deleted*ck up their spawn and create a future special fruitcake.
One issue with the modern world is that a lot of crazy people find other people who share the same kind of crazy. Instead of negative reinforcement, they get validation. As the liberty minded person, I believe a person can have any type of crazy notion they like as long as all parties are consenting adult of legal age. If you want to believe your gender is mayonnaise and you sexually identify as an Apache attack helicopter, that's fine.
Forcing your beliefs on other people is where it gets much more grey. I'm leery of the jihad to force everyone else to believe the same fruitcake stuff. Tolerance is not enough for a lot of folks, of all different stripes. Acceptance is not enough. Validation is what they want. Not "Fine, if you want to have your gender listed as mayonnaise, I don't care" but rather "Yes, mayonnaise is a perfectly valid gender choice, and you are so brave for embracing mayonnaise as your gender. Death to any infidels who deny your true gender!"
I've seen plenty of adults who screw up their children by forcing warped ideologies on them. And not just the special fruitcakes. Plenty of wacko religions have been doing so since time immortal. For the same reason. They believe their ideology is correct, and it is their duty to indoctrinate their kid instead of allowing them to evaluate such things on their own merit. It's not going away anytime soon.
