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.
