Did you even bother to read the page you link to?
It states in the conclusion:
"Did the Jerusalem Christians flee to Pella just before the Romans destroyed their city? There is no way to know for sure. We can only deal in probabilities. If we accept as reliable the accounts of Eusebius and others, the issue is settled...for when evidence is incomplete, selected and biased reading and interpretations of data can usually yield the desired conclusion."
How did this produce your statement "The fact is that over a million Jews perished in Jerusalem...whereas Christians en masse fled the city."? It's the ABSENCE of facts that makes the result unknown. The first clear reference comes from the fourth century church historian Eusebius. Yes, hundreds of years later a Christian historian says it happened, and from that you conclude it's a fact?
Maybe Christans did run away, maybe many non Christians did too, but there in no EVIDENCE whatsoever that this was done in obedience to any words spoken by Jesus decades before, therefore it cannot be said to be a fact.
