Well, these "I hate porn" people are extremely disingenuous, they're often (perhaps, paranoidly) pulling things out of their asses, or misrepresenting science... a lot... (more uncommonly) to try to come to a censorious position.
Also, censorship is about the most harmful thing that could be done, and it's not useful, and that is what they're about. They're not even remotely reasonable.
I don't really want to talk about specific people there, unless I have to. They're not worth it.
@olives I highly agree with the point of censorship. I'm Chinese, and I hate censorship. It's useless and harmful, especially to those children who don't know why people are talking in that way (to bypass the censorship) and think censorship is normal in life.
I suggest everyone who asks for censorship to move to China. That's what they deserve.
