Life, itself, can be ugly and vulgar.
When those in power stop listening to those whom they govern, what's the point of the unwashed deplorable masses being polite and civil? Civility becomes submission to those who want to control speech, thought, debate, and agendas.
Children and pets act out when their needs are not being met.
The needs of law-abiding, working American citizens haven't been met for a long time by the instiutions that alleged serve them and are run by their alleged representatives.
American politics is no longer a choice between Coke or Pepsi; we're left having to choose bewteen RC-Cola and Dr. Pepper. As a Pepsi drinker, why the hell should my choices be limited without my consent by paternalist elites?
I'm not buying what both party establishments are selling. If I have to pelt them with (rhetorical) rotten eggs and spoiled vegetables to get their attention, that's on them - not on me. Their willful blindness and their willful deafness is a choice they make to disrepect and to dismiss me because I am not conforming/submitting to their (false) narratives.
They don't want unity; they want conformity.
They don't want consensus; they want obedience.
We tried being nice, and they mistook that for submission and acquiesence.
The real ugly Americans are those who attempt to sanitize speech, thought, and debate.
