"Accusations of dual loyalty generally have an insidious, bigoted history," an early draft of the resolution reads in part. "The House of Representatives acknowledges the dangerous consequences of perpetuating anti-Semitic stereotypes and rejects anti-Semitism as hateful expressions of intolerance that are contradictory to the values that define the people of the United States."

Okay, let's look closely at that. Note the use of the term "generally." It quite literally means not always. Therefore, accusations of dual loyalty do not mean the accusations are insidious or bigoted but simply might be. It depends upon the intent and meaning of the accusation leveler. More important than all of that is whether the accusations can be substantiated.
Dual loyalty, per se, is not wrong. I have dual loyalties. I support the cause of right where ever. I'm loyal to that cause in the USA, Russia, China, Israel, Somalia, you name it. I'm loyal to my People, who are those who fight for what's right: the truth. Would I stand against the government of the USA if it goes against what's right, just, and the truth? I already have and will continue doing so. Do I have a higher loyalty to that cause than I do to the Trump-Pence administration? Of course. I only stand by the spirit of the law that is the US Constitution in defending certain things concerning the Trump-Pence administration against underhanded means to subvert that Constitution. Doing that is in no way an endorsement of Trump-Pence.
There are Jews in the US who have dual loyalty to Jews in what the Zionists have self-named Israel. They have that dual loyalty for the same reason I have and also add in closer DNA kinship, which is fine. I don't mind. I'm fine with that dual loyalty. What I oppose is dual loyalty to the Likudnik-type forces in Israel because those forces are opposed to democratic equality for the Palestinians. They oppose what we are supposed to have here in the USA: democratic equality, which is to say, one person one vote with equal protection under the law.
So, Ilhan Omar won't stand by those Likudniks. She's calling out others who are standing by them for being against what the USA is supposed to stand for. For that, she is my sister in spirit, seeking truth and speaking it to power. She is right, and her detractors are flat wrong.
