Yes it is censorship, it doesn’t matter if the scene shows something wrong. A lot of morally wrong things are in fiction: theft, threats of violence, people killed in fiction all the time, are drugged, mentally tortured etc. Just because you disapprove of one negative thing personally doesn’t mean it should be removed.
Pokemon X and Y have the villain plan to cause a genocide. In a kids game, where is the outrage? No one cares as it should be, because its a story, its not real.
The character itself is a minor, but you can romance a like a 45 aged guy. But they didn’t remove that or any other over 18 romance involving the main character who is a minor. And i am only saying this to make your point mute, because again it doesn’t matter. If you really held such high morals you would have kissed this website goodbye long ago because it contains a lot of explicit material involving minors or are you just pick and choosing when your morals apply to fit current agenda? So you can save your “moral high ground”.
