The most perturbing question for the liberal is the question of violence. The liberal’s initial reaction to violence is to try to convince the oppressed that violence is an incorrect tactic, that violence will not work, that violence never accomplishes anything.
The liberal is so preoccupied with stopping confrontation that he usually finds himself defending and calling for law and order, the law and order of the oppressor. Confrontation would disrupt the smooth functioning of the society and so the politics of the liberal leads him into a position where he finds himself politically aligned with the oppressor rather than with the oppressed.
The reason the liberal seeks to stop confrontation — and this is the second pitfall of liberalism — is that his role, regardless of what he says, is really to maintain the status quo, rather than to change it.
They’re just defending the status quo, while nominally supporting The Current Thing TM to look cool on social media.
