Morality is stupid and made up. Level up your critical thinking skills, stop using "morality" as an intellectual crutch.
99% of modern morality is "because I said so". If that's the level of thinking you're applying to things, then you are a stupid person. Sorry.
There are plenty of legitimate arguments against porn. "Ughhh sex icky!!" is not one of them. Purity is not an argument. Religion is not an argument. Saying something is immoral is not an argument.
