This is why this sort of useless regulation is genius. No one is going to sign a petition to protect step-porn. Since it would permanently exist in a public archive, our great, great, great grandchildren would think we were freaks. "We don't know much about great uncle Johnathan, but he liked watching step-siblings fuck."

Honestly they all kinda missed the boat when it comes to the "morality" vote, Boomers are dieing and Gen X while still having a lot of folks who want to be just like their parents, isn't as big a voting block. As for the newer generations studies show that they hold on to liberal ideas longer then previous generations and morality in the biblical sence isn't as important. Sure some shit will get passed, but I honestly feel they are in their death throws, (some things take a while to die and can fuck shit up in the process) I think this is why they seem to be more openly embracing the incel community, they need voters to replace the Boomers, on a side note this is also why I believe the LDS church seems to be backing the "tradwife" influencers, but that is mostly conjecture.

Opposing this isn't defending step porn - it's opposing illegalizing using minors in porn.

If it were actually about banning some kind of consensual porn between adults, then you'd be defending step porn by opposing it.
