some conservatives are going to have things blocked that aren’t porn and are helpful to some kid’s sexual education because they’re regressive.

That sounds like the real motivation for this nonsense: not to protect kids from harm, but to protect their parents from the responsibility of properly educating them.

as people say for hate speech laws: "if you aren't wanting to show children anything sexual, then there shouldn't be a problem. what do you wish to show kids that you think may be considered sexual?"

naturally gov overreach is a concern even for speech but that doesn't stop people from trying to regulate speech.

I think ultimately though with the system in place mentioned, it wouldn't completely block access to educational materials as parents could easily show that stuff to their kids if they so choose.
