Reductoid 

The name for a person who fails to engage with the nuances or complexities of a controversial discussion, and instead takes the easy route of resorting to paint the opposing side with universally condemnable titles, such as "racist", "misogynist", "marxist" or "Nazi".

Reductoids espouse such judgements with an unfounded air of certainty and moral superiority, and often do so when they are incapable of reason.

Greg - "Well actually I believe that trans women should compete in male sports categ-"

Reductoid - "TRANSPHOBE"

Greg - "You didn't even get to hear out my argument, it is in good faith"

Reductoid - "Transphobic piece of shit, why do you hate trans people?"

Greg - "I don't hate trans people, you are being such a reductoid right now"

harm reduction

The practice of providing advice and helpful suggestions to a novice regarding potentially dangerous activities in the hope that they will heed the advice and not cause hurt or harm to themselves or others.

Practicing harm reduction Keith showed Brittany how to IV drugs. According to him he didn't want the wrong person showing her the wrong way, because he knew she was headstrong.

reduction of order 

Reduction of order is a technique in mathematics for solving second-order ordinary differential equations. It is also a technique used in restaurants by math geeks who change their order to an amount less than originally requested.

I went to McDonald's and ordered two Big Macs, but I changed my mind and ordered only one. They didn't like my reduction of order.

Reductio al Gore 

Reductio al Gore is the argument tactic of dismissing all the science and evidence in support of man's contribution to climate change by invoking the name of Al Gore. It is a type of logical fallacy.

"I don't care that 97% of climate scientists support climate change because Al Gore makes money and I don't like Al Gore. Therefore, climate change is a hoax."

"Is that the best you can do? You don't have evidence, just a Reductio al Gore."

Reductio ad Absurdum 

A process of making something stupid because that is what Google says it is.

For Example: If you put “Reductio ad Absurdum” into Google Translate it detects the language as Latin, and translates it to English as: “Reductio ad Absurdum.”

Another Example: For years (through May 29, 2018 at least) if you ask Google "What does it mean to be an American?" it responds with this as the first answer (in a box even):

"It means that I can say "The Pledge of Allegiance" and that I can vote for the President, my county clerk, and the Mayor. But to me it means most of all to be free and to be proud that I live in the United States of America here in Wisconsin."

Dig deeper and you'll find it is written by an 10-year-old who, in addition to thinking that the U. S. is in Wisconsin, does not know that to be an American means she is free to NOT say the pledge and that she has 10 years to go before she can vote.

Thank you Google for establishing a 10-year-old as the #1 expert on what it means to be a patriot. Way to go.

If we're going to Make America Great Again we've got to stop all this Reductio ad Absurdum going on.
