Ellis Island has a crematorium and a delousing chamber (the US also used Zyklon B to delouse Mexicans on the southern border). Does that mean a genocide took place there? Oh wait, they don't have the shoes and hair. Because that's rock solid proof of a genocide.

Everyone in Germany was starving toward the end of the war, and obviously that is going to include internees. Nobody denies that Jews were placed in camps, what they deny is that there was any sort of program of extermination. Witness testimonies are the least reliable form of evidence. There are no documents describing any extermination program - the Holocaust operates as a conspiracy theory, and the official story relies on Pizzagate-tier coded language. Nobody has found appreciable levels of cyanide residue in the supposed gas chambers, only in delousing chambers. And testimonies extracted through torture are of little value. The Holocaust narrative does not survive based on the sheer strength of the evidence, but instead relies on propaganda, social pressure, intimidation, and legal force.

And there's a reason why Jews decided to place their ethnostate in a sea of Muslims - historically, they have gotten on much better with Muslims. They hate and/or fear Christians much more. The Jewish identity is fundamentally rooted in the rejection of Christ.
