Well it's obviously not the originally intended message, but the idea is that "crybullies" get their strength from weakness, in the sense that it gives them a feeling of moral superiority due to victimhood. They then use this as a platform to attack opponents. "Punching down" is the worst sin in the modern liberal conception of morality, so if your peer group consists of those people (and that means, nearly everyone in the middle and upper classes of modern western society) then you can very effectively have someone shunned by the group if you paint them as an oppressor. It doesn't appear to matter how tenuous those claims are, if the purported victims are sufficiently weak.

I don't agree with your original analogy, but everything you've got here sounds spot on.
