That is the censorship of a political idea - that the government has no place censoring depictions of what is responsible for every human being's existence masking itself as "morality" and "community standards". "But advocating it is still legal" would be no more valid an excuse than making displaying or depicting police misconduct illegal but nominally allowing advocacy against police misconduct. The point of censorship is enforced ignorance to maintain control.
