And the younger ones are genuinely that stupid, because they are surrounded by stupidity-generating sources of misinformation.
I strongly object to the notion that children and young people believe in gender ideology because they're stupid or lack critical-thinking ability.
Nowadays they are fed all sorts of nonsense about gender identity based on sexist stereotypes from the start of primary school, and why would a child not believe what the trusted adults in charge of their education tell them?
Then, as kids get older, they risk being ostracised by peers for speaking their mind around these issues and asking sensible questions about women's rights, so they quickly learn that questioning gender identity is so taboo that it's best to follow the party line. Often they also have friends who are trans or non-binary, and so it also feels like a personal attack to question the accepted narrative.
Young people aren't stupid - they're the victims here just like the rest of us.
IMO, not recognising young people as victims of gender ideology here is dangerous, as it moves the focus onto their behaviour and diverts attention away from the subtle but insidious ways that children became indoctrinated (through sexist stereotypes and misguided SRE in school and woke children's books). And if we're not acknowledging that children are being damaged and misinformed by being taught gender ideology as fact in school, then how will we challenge it?
