Does everyone in these comments not realize the tactic?

The rules is people get to speak their mind.

The rule is based on the understanding and underlying premise of civility.

The rule is then exploited by the uncivilized.

When people recoil and react to this, the uncivilized call them hypocrites.

The civil are disarmed in conversation, leaving only a feeling of being silenced in your own homeland. That leads to subjugation by the people exploiting the rule OR extreme violence when silence cannot be abided.
