Yes, there are - in a sense - righteous jews. ~5% of jews worldwide are professing Christians, so in the only way we can really be righteous, they are.
The "Synagogue of Satan" you've quoted many times has nothing to do with fake jews or anything happening today. There is no real sanhedrin, and the nation of Israel is mostly secular, godless, and almost hopelessly lost and wicked. None of that changes that they are God's chosen. But they still have the culture, language, formalities of the people from 2000 years ago. They cannot practice their religion, so they made up a way to try to practice. That's not "tranversing" anything, it's stating a fact.
They were told to practice it in a very specific spot, in a very specific way, using very specific items, and they aren't doing that. God didn't give them a plan B. So by default, anything they're doing today cannot be a true practice. When they once again do those things the way and in the place the Bible describes, you'll know that you're almost at the end.
Of course "Jewish" is an ethnicity. The seed of Abraham, Isaac, Jacob, whittled down to the tribe of Judah and those who stayed with him when the nation split. My thoughts and what I have or haven't thought out on the subject are irrelevant, God's word describes them in detail, Paul spoke much about Jews, their past, and their future. Converts to Judaism were 2nd class citizens, who could not enter the temple as ethnic Jews could, so it is first and foremost about their bloodline, not their beliefs. When someone who was a Jew was called "not a jew" in scripture, it was an allegory for the state of their heart, not their racial identity. Just as the bible speaks of the heart being circumcised, it was referring to salvation, not a heart procedure.
How important is the Jew? Christ told them that they would trigger the 2nd coming. When the leaders of Israel rejected Christ for the final time, he told them "ye will not see me again til you say blessed is he who comes in the name of the Lord", an OT moniker for the Messiah. In other words, Jesus told the Jews they would not see him again until they called on him as their messiah, which they will do just before armageddon. Read in Daniel, why is there a 7 year Tribulation, which he referred to as "Jacob's trouble"? Because the primary purpose of that awful time is to bring Israel to their messiah. Not to bring Cincinnati or ETNVOl to messiah, because that's what the last 2000 years has been about.
Why do jews dominate entertainment, law, medicine, etc in America? I can only assume because they're blessed. When God blessed Abraham, he made his descendants of promise special. The prominence of Jews at the top of many industries bears that out. But if one is a non-believer, those gifts are a curse rather than a blessing, because to whom much is given, much is required. As for those of us who aren't from that seed, we're told we're blessed if we bless them, and cursed if we do not. Which should make anyone who has antisemitic thoughts tread lightly.
