You are putting words in my mouth, maybe think about phrasing your points in a less personal way in future?
I don't actually see watching porn as immoral, although I am aware that there are a large number of people who do. Hence my surprise that so many people were willing to tie their identities to it.
Philosophy is real. But if you knew anything about philosophy, you'd know it's not "this is immoral because I say so".
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.
That watching porn is still an immoral act is implicit in your surprise.
