Holocaust website can’t explain why the Holocaust happened

With nothing better to do, I logged onto this website:

The Holocaust raises many perplexing questions.

The following quote is from the website, cited above:

Why did so many ordinary Europeans cooperate with Hitler’s programme of Jewish persecution (actively or passively), and why did relatively few resist?

Was the systematic murder of Jews on an industrial scale an anomaly of history, or merely the worst manifestation of a hatred that for thousands of years has simmered and frequently boiled over?

How was it possible that a “Christian” society as highly educated and cultured as that of 1930’s Germany could spawn such evil?

Shadows of Shoah [website], alone, cannot provide satisfactory answers. It can and does, however, convey some of what happened and, importantly, it provides a human face for what has become, for many, merely a faceless statistic.

What did the Jews ever do that caused so many non-Jews to hate them? The Jews have never done anything wrong in the entire history of the world, so why do so many people hate them?

This news article tells about Donald Trump’s Holocaust Remembrance Day statement:

The Donald failed to mention Jews in his Holocaust Remembrance Day statement.

The following quote is from the news article:

Begin quote from news article:

The resolution, a shrewd effort to pin Republicans down on something the Trump administration has needlessly made an issue, condemned the White House’s Holocaust Remembrance Day statement, which failed to mention Jews or the anti-Semitism that led to Adolf Hitler’s genocide against them. It also called for the House to reiterate “the indisputable fact that the Nazi regime targeted the Jewish people in its perpetration of the Holocaust,” condemn Holocaust denialism, and demand acknowledgment from the White House that Jews were targeted.

In the wake of controversy over the Holocaust Remembrance Day statement, the White House defended it, saying that it had wished to be inclusive by acknowledging that other groups had been killed by Hitler’s regime as well.

End quote

So-called “other groups” who were killed by “Hitler’s regime” don’t count. The Holocaust is about the Jews. Why didn’t Trump’s Jewish son-in-law advise him on this subject.
