Because people who deny the holocaust inevitably tend to say that the Jews made it up to garner sympathy and as a justification to create the state of Israel, then usually start rambling on about how the Jews get kicked out of every country they’re in for undermining the state, spout Zionist conspiracy bullshit, and claim the Jews (along with George Soros and the Clintons) are secretly trying to create globalist union, and other such nonsense.How does denying the Holocaust promote racial hatred?
Are you really not understanding this?
