Why do people still believe in the Holocaust?

Can someone please explain to me why everyone's expected to agree with the official story about 6 million Jews being killed under the Third Reich?  I mean, in many countries, it's criminal to even *question* the idea that something might be wrong with that claim.  And you basically get blacklisted everywhere for doubting it, being labled as a denier.

I've done some research on this, and there's actually a pretty solid case that there was no so-called "Holocaust".  One that I agree with, in fact.  Here's an example of an excellent debunking:

So, with a case that solid, why is it such a big deal?  Why do people believe that there was a Holocaust?

The question is not "why do people still believe in the Holocaust?"  The mass murders by the National Socialist regime in Germany were well documented.  Mass graves were found, and so fucking what?  Woe to the vanquished.  The victors write history.

The question you should be asking is, "what makes the kikes so special that White Western men should have died for them, when four million White Christian Armenians were murdered by the Turkish government barely a generation before, to which the West's response was a deafening silence? when thirty million Ukrainians were machine-gunned by Stalin's kike-heavy NKVD barely a few years before the war began, likewise ignored by the West and outright denied by influential Western newsmedia (Jewsmedia) like the New York Times for decades afterward?  Why did six hundred thousand Americans have to die as mercenaries in the kikes' cause, a war to save the kikes from a fate they brought upon themselves?"
