I don't know.
For one thing, I think the above was a perfectly valid question. I used to wonder the same thing, until I read Rise and Fall of the Third Reich and came across where the name came from, and some of how it was justified at the time. IMHO the cheif tactical error that question made was to pose it in present tense, rather than past tense. If they'd fixed that, I bet nobody would have complained.
There are a fair number of questions I see posted that are about modern-day events and are essentially political or sociology questions, not proper history questions. If there were SE sites covering those topics, we could just shunt them off there and be done with them. In the absence of a Sociology.SE though, I suppose you could view History as Sociology carried out on past events and peoples. There's nothing stopping a person (eg: us) from using the same analysis tools on today's events we use on past ones.
We could instead say that anything the oxymoronic tag
contemporary-history can be applied to (currently 8 questions) is off-topic.
Perhaps the best thing we could do is come up with a special tag for such questions, so people who don't like them can avoid them (or see if it can be improved into a real history question). Unless someone says otherwise, I think I'll start tagging all such things
contemporary-history. Since its sort of an oxymoron anyway, so that ought to be a nice flag for those in-the-know.
I'll throw up a counter-example: What happens after a widespread social chaos. By most measures this would probably end up being an off-topic question. It's about present day events. It's very political. But the poor questioner is trying really hard to find himself some hope out of his present horrible situation by looking at history. If there is something we study history for (other than sheer fun) this is it. Most of the answers are IMHO (leaving mine aside) high quality attempts to enlighten. I really have a soft spot in my heart for this question, and would hate to see it have been uncerimoniously closed because it isn't Ivory Tower enough.
