Jews inherited the Truth. Why would any Jew deny Hashem?
They worship the love they get from other leftists for being a good leftist more than Hashem. For instance, one of their beardless "Ravs" whose name should be forgotten said that the story on Purim that Esther also said to kill Haman's sons must have been a metaphor, or else Hashem would be evil. This of course means he's calling the mitzvah to wipe out Amalek evil, but more insultingly, Hashem.
This is done because not killing a bad guy looks great to leftists, and so he spits at Hashem to look good to others who want justification for their spitting.
