Putting “people” in scare-quotes while spewing inhuman and downright unpatriotic rhetoric is certainly a choice.

No, dual-citizenships do not cause people to be “foreign agents and dissidents”, and further, to be a “dissident” is a human right that this country was founded specifically to preserve and defend. Welcome to America, where dissent is our Constitutional right; if you don't like that, you can leave, instead of trying to invoke “wartime laws” to impose your anti-American viewpoints on the rest of us.

Have you ever considered getting a second citizenship yourself? I can think of quite a few dictatorships where your attitude would be lauded.
