As far as slipperlyslope, I suggest you look up the slipperyslope fallacy and why arguing some dire future condition possibly existing isn't an argument against a sepecific and scoped proposal.
> If you think porn is on the same order of harm as alcohol, you need to lay off the sauce.
I have no idea. Both ruin relationships or prevent healthy ones. But alcohol makes you fat, harms your organs and can lead to diabetes in the long term so I would say physically harmful things like alcohol are much more harmful than porn but that is bad whataboutism because even though you are right about alcohol that does not make porn any less harmful.
I'm sorry, this is losing the point a bit, but there really is something so telling about the projection behind "fantasy [bad]" and "you might have fantastical thoughts".
Yup, some of it's a bit wild, and I hope everyone has the joy of a partner to safely explore and experience that with, sans judgement.
