Oh and there are other anti-Americans in Congress such as Steve King and if Roy Moore won he would have been an Anti-American senator .
Your whataboutism is irrelevant, especially when what they've said isn't comparable, & especially when she isn't even anti-American.
You're tilting at windmills. The real reason the right thinks (and says) Omar is "anti-American" is that:
-she's not white
-she's a woman
-she speaks out against them
All the rest is just excuses.
Remember, when the right-wing says "Anti-American" what they mean is "Anti-Republican". Because to the Republicans, "America" isn't about a set of ideals, it's about them being in charge.
For Republicans, as with their criticism of Omar, all the rest - the Constitution, the Declaration of Independence, two centuries of (imperfect) support for freedom, civil rights, and a better world - are just window dressing for their real agenda: them in charge, forever. If you want a perfect demonstration, look no farther than Mr. Trump, and how the Republicans have abandoned their positions on everything from Russia to the Constitution in order to support him.
