Edit: Child evidently has a reading comprehension problem and didn't understand "don't have to be a puritan." The emphasis is on cyberpimps. Whether or not you approve of pornography or prostitution you can still find pimps, who are by nature exploitative, distasteful without being a puritan.
It’s the objection itself not the reason for it that’s important. In other words objecting to porn on artistic grounds is still puritan.
Ergo,
>objecting to porn on artistic grounds is still puritan.
is not true
It’s defining something as positive or negative which makes this a moral judgement not the specific value assigned.
I use positive/negative here because someone may believe there’s an incorrect solution to a math problem without judging such errors in terms of morality.
