It's a worthwhile first step when the conditions are right, but there's a huge problem this piece fails to address: where the "awakened" person's next steps lead them.
A vacuum forms when a person's ideology (which is a portion of their personal identity) crumbles. They will grasp for literally anything to feel safe and whole again, and that spells danger if they don't have enough understanding of history and current cultural context to make an informed decision. (In fact people reaching this point on their own without checking into any historical context is probably how a lot of today's MAGA-esque groups started growing.)
At the same time, we can't just tell people what to believe, either. The easiest step is discussed here. The most crucial steps are missing.
