There is a Wikipedia page for “alternative facts” already
In what is certain to become the most-edited page on Wikipedia since Pepe The Frog, “alternative facts” now has a home on the internet’s vast free encyclopedia. Helpfully noted as part of a series on “misinformation and disinformation,” the page, at present, begins with a careful recitation of the phrase’s origin story, in which White House press secretary and Dippin’ Dots hater Sean Spicer presented multiple outright lies during a press conference about the shitty turnout for Trump’s inauguration, then did not take any questions, a performance that stand-up comedian Kellyanne Conway described as merely presenting “alternative facts.” (We now know that both were acting on a direct mandate from the commander in Chief, who has been reported as spending his first week in office fuming about the low turnout and demanding his subordinates respond like this, despite advice to the contrary.)
