Not that I expect any christers to realize this
Christianity bears primary responsibility for historic antisemitism. Few ideas can have been as poisonous as, and inspired more murderousness than, the idea that Jews were the Christ-killers
Jews had enemies throughout their entire history. However, indeed Christianity does bear great responsibility because in some times, and in some areas, Jews were persecuted and had to fight to retain both their faith and their lives.
It appears that if Jews recorded anything about Jesus during his lifetime, it did not survive. After his death, they wrote nothing of Jesus until several hundred years after his death. And even then, it appears to be in response/retaliation to Christian criticism/harassment of Judaism.
Instead of being introduced to Jesus in his own time and faith, they were introduced to him as the leader of a powerful group seemingly intent upon destroying them.
Instead of leaving the Jews with this picture of Jesus, we owe it to both Jesus and Jews to present him as he was in their day: An advocate of Jews who lived in poverty and who lifted back up (to Judaism) those who were losing their faith. Jesus was/is not a madman leading a powerful army of angry Christians.
