You could've distilled your answer to the question by simply saying, "Pure speculation based on a faulty assumption that only US citizens are on this list".
So are you saying you're just guessing because you believe the government has it out to get Trump supporters? If, it turned out, there was a similarly large number of people on the list prior to Trump's election, would that change your mind? I think the concern that an extra-judicial list this large certainly has the potential for abuse, and America's 3-letter agencies have historically used the auspices of national security to target and harass political opponents and personal enemies. However, you don't have any reason to suspect that this list contains that group specifically, right? Other than just some perceived marginalization by mainstream society, that is.
