Research (background reading) for the question Are rape vans real? is unpleasant.
I found evidence for an answer in the affirmative: Snopes and Wikipedia identifying (and/or narrating) a criminal case involving rape, torture, and murder.
Is this a topic people want on the Skeptics site? On the StackExchange network?
For example this meta-answer about 'rape' says,
The rest is actually tolerated (of course, if it's not brutally gratuitous!)
Does that mean "brutally gratuitous" isn't tolerated? Is this topic "brutally gratuitous" and therefore intolerable? Although free speech is protected in national law, can I flag this topic as offensive,
This question contains content that a reasonable person would deem inappropriate for respectful discourse?
Or, if I shouldn't flag this topic for moderator attention, am I allowed to vote to close it just because I don't like it? For example I could invent a close reason like the following to claim that,
This question is off-topic because it is indecent and offensive.
That I could simply vote, and the question would be closed if enough other people in the "community" agreed.
