Complete human beings with enlightenment and wisdom would never find the reasoning you mention to be convincing or tempting. Because they are complete, they would not be suckered into this type of false dichotomy. They would have none of the personal vulnerabilities on which the deception of false ideas is built.
False ideas don't require personal vulnerabilities. Any attempt to engage with the world produces false ideas, because we are ignorant and fallible beings.
Personal wisdom and enlightenment can reduce one's vulnerability to manipulation, but it does not answer political questions. It can tell me why I'm scared, but if my fear is based on the prospect of an undesirable outcome, spiritual wisdom cannot tell me whether the outcome is plausible or likely. Even if you reject fear as a basis for thought and action, you will still find yourself agreeing with it quite often. For instance, assuming you have not yet achieved perfect enlightenment, you are probably scared of injecting heroin. You were manipulated into this fear by information and media provided by people who want you to be scared of injecting heroin. Spiritual wisdom allows you to realize that you are scared and manipulated, but it does not answer the question of whether or not it is a good idea to inject heroin.
In general, there's no way to dodge the necessity of examining everything on its merits, and no way to get out of the catch-22 that all the information you consume is produced, directly or indirectly, by people who care about what you do and believe. Rejecting all self-interested manipulation would mean rejecting almost all human interaction. It would certainly make it impossible to learn anything about politics. As for fear, you can reject fear, but you can't simply say, "Fear is on one side of the issue, so I must be on the other." The presence of fear is informative, but it is not that informative.
To go back to the example at hand, wisdom cannot advise me to ignore the issue, nor can it resolve the issue one way or the other. After all, the bogeyman prospect is a story of how the current legal system is vulnerable to exploitation and how that will affect American business. Wisdom helps, but not the kind of wisdom you're talking about. The issue must be approached by seeking information, reading opposing viewpoints, and discussing it.
