Why are people so nasty to Jews? What did they do?

They goddamned Jewed me, that's what they did!!

In reality, very few people are nasty toward Jews. Usually only full blown white supremacists. Rather, right wing Jews use accusations of anti-Semitism and/or Holocaust denial to shut their political opposition up.

Or have you never thought it strange that Hitler was on the extreme far right, while most of the people these days who are accused of similar levels of anti-Semitism are on the far left? It's a political tactic and it has nothing to do with Jews. It's about smearing the opposition.

Go read some history and it’ll help u understand. Jews persecuted Jesus, invented Usury and Jews killed off the old Russian royalty in the Bolshevik communist revolution. Not mention Israel commits border crimes daily.

Many doctors are Jewish, and they are not hurting anyone.

lol, many doctors are hurting people whether they're Jewish or not. They want to sell you drugs and surgery to pay off their yachts.

but because I am a Christiannnnnnnnnnnnnn (follower of Christ), who is Jewish, I am not allowed to speak ill of Jews or Israel.

Jesus himself spoke ill of Jews, he thought that many of them were corrupt and not true believers. Disliking individual Jews is not the same as hating Jews in general.

Not only are you "allowed" in christianity to "speak ill" of Israel if it becomes corrupt, but whether or not christianity allows you to do something shouldn't even factor into it because christianity is just an irrational belief system with no basis in reality.

I as a centrist, do nnnnnnnnnnnnnot agree with any far left or far right government, in Israel, US, or any other country,

Israel is far right. You are also not a moderate or a centrist because you say purely right wing things such as "leftists are professional victims" and "Hitler was a socialist". Only right wingers say those things.
