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?

True, but the doctors and engineers stay in Mexico.  It's the illiterates, the retards, the thieves and felons and drug addicts, the ones who can't make it where they are, who cross the border and put their hands out for "el guelfare."
