A complete and total idiot who doesn't know what the fuck they're doing half of the time

Ashley: So we were playing basketball and they started yelling at me for kicking the ball I was like "then how do you make it in the hoop silly" boys are weird.

Melinda: Dear God, Ashley you are Such a fucking ignorancer.

Tribal Ignorance 

The human condition whereby the primal need for identity and trusted association, prove to be more important than objective, critical thinking; and the quest for goodness, righteousness, and truth. Often magnified by a parallel lust for control, capital, and power.

It’s tough to explain why politicians will put party before country; my only explanation is that it is an example of tribal ignorance.

ignorance is bliss 

It is a term used to falsely justify apathy on the given subject in the form of a catchy cliche.

A prevalent saying of the people in North America when confronted by the truth.

Me: Did you know that fluoride causes bone brittleness and dental fluorosis?

You: Meh, ignorance is bliss. *swallows the toothpaste*

Radical Ignorance 

The original name of the Make America Great Again movement before they came up with something less self-deprecating.

Let’s come up with something a little more patriotic sounding, I’m afraid that Radical Ignorance just doesn’t cut it.

Fact-proof Ignorance Bubble 

The hard shell that surrounds the head and brain of all Trump supporters.

The decline of education in America and the coinciding rise in more Americans afflicted with the Dunning-Krueger syndrome is strong evidence that many people live in a Fact-proof Ignorance Bubble, free of rational thought, logic and common sense.

Trying to discuss world events with Trump Supporters is useless since they live in a Fact-proof Ignorance Bubble.

Weaponised Ignorance 

The creation of far-reaching, pervasive and destructive policy based upon unbelievably unreliable, unpredictable and/or otherwise ridiculously, unsubstantiated, merit-less untruth.

Current example of Weaponised Ignorance in a time when airtravel has NEVER been more safe: These new-fangled airplanes are just waaaay too complicated for pilots to fly. Too many buttons and switches to deal with. We need to bring back those old-school airplanes with them 'flappin' wings' and git rid of all these new ones with the com'puters...
