You are indeed right. It seems to me that when one is writing about more serious topics that the responsibility of the writer, to do justice to that topic, is higher. It's not something to undertake without a good base both in being knowledgeable of the subject and being, at least somewhat, able to handle the craft of writing.

That may seem like censorship. It's not. It's merely a decent respect for a sensitive and important topic. There are certainly others, in addition to rape, molest, severe neglect, abuse. One other, well-included in the HP world is war.

I would, for example, strongly recommend that anybody, before writing about, say, war or rape, not only read but talk long & honestly with someone who has experienced this, perhaps not only one or two people.

I would promise these writers that it would change their views, it would mature them, and their writing would be more respectful for it.

We are very much in agreement.
