I would say most of us are more agnostic about it. "It could be true, it could also NOT be true, we'll know for sure within a decade."
Believe it or not, we don't actually want to kill Jews. Just like I do not want to see the white race extinguished, I also don't want to see another of God's creations -- the Jewish race -- extinguished.
If the alt-right were in power (within a decade, as mentioned), we would merely remove Jews from holding jobs in news media, academia, and probably finance.
