Go back and read what I wrote again, especially the deliberately emphasised "in the mind of the Muslim". That's a big hint that I'm talking about perceptions, not objective reality. A "single point in history", to use your words, can and has easily affected the viewpoints of millions, even billions, of people. There's no law that says perceptions must be correct, accurate or helpful. In the context, "do X or I'll fetch Y" is either coercive or not depending on the addressees beliefs about whether Y is a threat to them or not. Thus in discussing possible coercion you have to take the perceptions of the potential coercee into account.
