Martin Luther. The Anti-Semite father of Christian Protestantism
“Moreover, they [jews] are nothing but thieves and robbers who daily eat no morsel and wear no thread of clothing which they have not stolen and pilfered from us by means of their accursed usury. Thus they live from day to day, together with wife and child, by theft and robbery, as archthieves and robbers, in the most impenitent security.”
This was mindblowing to me a year or so when I first discovered it; the father of Christian protestantism, Martin Luther, virulently hated Jews and authored the work The Jews and their Lies, (of course only available free on the internet despite being written in 1543). This point is so great, I will leave it for the reader to ponder without comment.
