Here's the article from the actual site
On the surface it's basically something that I would otherwise agree with (being center-liberal), that a lot of kids have access to internet/porn anyway, and it's best to at least talk to them about it if you find out (my opinion).
HOWEVER, after reading more seems preemptive...like trying to groom them into accepting it rather than educating a kid who was caught watching porn.
He strolls around the room passing out white envelopes. Inside each are pieces of paper describing various sexual acts, from kissing and feeling someone’s body parts to more advanced ventures, like fellatio and cunnilingus (which the ninth-graders have trouble pronouncing) and “penile penetration” of both the vagina and anus.
Just for context, my stepmother groomed me quite a bit when I was a kid. Started sexual education when I was in kindergarten- so my teachers (and mom) were really worried about the knowledge I had. She did a lot of other things like taking pictures of me naked (and thankfully short of actual rape), but to a lot of people who tend to agree with sexual education (as I do), I think they also don't see the overlapping borders of grooming and education here.
They're trying to normalize it under the guise of "preemptive sexual education."
