You don't have to sell it like that. The bill that needs to be passed is default presumption that all websites on the internet not explicitly marked as such and who voluntarily accept a higher legal burden and standard of moderation may contain content not suitable for children. And that is up to parents to control their child's internet access to limit their usage to only these sites.
Because I don't actually care about pornography, if it magically disappeared I wouldn't really care, it's all the other "not suitable for kids" content I care about that will get caught up in these laws. I don't want to give gross concern troll political groups moralizing about their precious hypothetical children the legal tools to ban what they don't like.
Ive had massive amounts of trouble convincing people that pornography is just the tip of the iceberg. That's why it's such an effective tool for broaching massive-scale surveillance: the architects of these laws have said that they want to be able to police all content with these laws, and anyone who tries to speak out against them can be painted as a pervert who hates the safety of kids.
