The problem is really two fold when it comes to White Nationalism and Jews.
Many White Nationalists believe 99% if not all Jews are in on a conspiracy to destroy White countries, etc by polluting them with hordes of nonwhites.
There are some Jews that are involved in this, but there are also a lot of disgusting Gentiles that are involved in this too. Ted Kennedy for example was one of the worst offenders, and he wasn't Jewish. I think they show their anti-Semitism when they blame ONLY Jews for these problems and fail to see that there are evil Gentiles that are also involved in evil movements. Notice they always talk about Marx but rarely Engels. Blame rests on both evil Jews and evil Gentiles for the current mess.
Quite a few Jews are loony leftists(although hardly all) who would be happy about this.
They're not really following the Bible though if they are loony leftists, and as such they're not really representing Judaism.
In order to reach a common ground two things need to happen:
1. White Nationalists need to be sane when it comes to speaking about Jews, I don't mind criticism(as a part Jew myself) but I do mind the belief that all Jews are the "eternal enemy of the white race".
Yeah it's that kind of BS that really is frustrating.
2. The Jews who aren't loony leftists need to loudly refute the loony leftists when they attempt the typical Nazi/"white supremacist" smear used so often.
Jews who think Israel will be spared from this rot of "diversity" are fools, Israel will be going the way of every White country unless things change so its in our best interest to work together.
It would help if more Jews were like Chaim and spoke up against left wing thought, but some people will hate Jews no matter how righteous they are. Anti-Semites hate Jews because they hate God and Jews in a way represent that God is real.
