Why were the jews stigmatized as outsiders in europe during the middle ages? ?

The Jewish people were stigmatized that time and they were treated as the Christians’ worst opponents. The Christians in Europe were terrified that the Jews would spread their teachings. If this happens the Christian belief would lose supporters in the end. Jews were deprived of getting hired for jobs that time, too, even though they are skilled enough. 

the statement the greek philosophers aristotle and plato would be most likely to agree with is statement c, a countries leader should be motivated by the common good of the country.

he killed a bunch of jews so no one was spending money and the stock market rose again
