The arbitrary 18+ line for adulthood is a joke. Tell me the vast majority of 18 year olds are able to make a truly informed decision to castrate or sterilize themselves. You also can’t go around saying transsexualism and homosexuality are perfectly fine—for 18+ year olds—and expect that line to shift over time, affecting children.
Homosexuality and transsexualism are BOTH mental disorders, against the God created, natural order of things. Homosexuality is not A-OK. We can tolerate it among consenting adults, but it’s a socially negative act that deserves society’s opprobrium. Same thing with this trans nonsense. We don’t “affirm” anorexia or other types of body dysphoria. The fact that some adults are willfully choosing these paths doesn’t mean the rest of society needs to applaud those decisions.
Any age chosen for the age of majority is arbitrary.
