Whole families were murdered and had evidence of their existence destroyed in the Crusades, Inquisition, etc..
I can believe the murdering part, but I can't see officers of the Inquisition or the crusaders ferreting round for people's personal correspondence, household bills or birth, marriage, and death records in order to destroy it all. They would have been too busy doing that to actually find time to kill anyone. ;-)
but since all the records were destroyed, you have none whatever evidence that it wasn't so, do you? :)
But were the records all destroyed? ;-)
The Spaniards wouldn't have wanted proof that Jews who didn't believe in Jesus were ever in existence in Spain.
If that is so, why do all know about medieval Spanish Jews and admire their huge achievements? I'm serious.
You can be really evil and Anti Semitic.
I probably can (never tried to), but I am not. I am simply not kowtowing to whatever you say just because you call yourself a Jew. Your being whatever ethnicity / nationality / religion has absolutely nothing to do with being automatically right on any subject.
