Republicans (especially those in Congress) now must face the objective reality that they have publicly supported a lunatic who threatens violence against the government they say they want to control. As long as they allow MTG to spout her evil from a seat in Congress, they risk losing their whole party's relevance in national elections. There have been other objectively real political party crises in our history--
--Nixon's Southern Strategy in which many racist Democrats decided they were no longer wanted in their party and so became Republicans (probably winning Nixon the 1968 election)
--The Dixiecrats who were repulsed by Truman's civil rights progress (things like ending segregation in the military, for example) and ran their own slate of candidates, winning 39 electoral votes in 1948, The Democratic Party stomped out the last embers of that revolt by the 1952 election.
--The 1856 breakup of the Whig Party, in which the abolitionists could no longer support the party compromise positions on slavery and then formed what we now call the Republican Party.
-The Mongols believed in the objective reality where they had the right to ransack the world and kill civilians
-The Crusaders and the Caliphates believed in an objective reality where their God commanded to them to win the holy land
-The US held an objective reality in Manifest Destiny entitling them to displace anyone from coast to coast that stood in their way
-The Spanish Empire held an objective reality where it had the right to conquer and convert in the name of God
-The British Empire believed in an objective reality where they had a white man's burden to civilize the world
-The Confederacy believed in an objective reality where slavery was a moral good.
-The Russian Communists believed in an objective reality where they could build a worker's paradise
-The Nazis believed in an objective reality where they were the master race and subhumans existed.
-The segregationalists believed in their objective reality that whites were better than blacks.
-The Chinese believe in an objective reality where all Uighurs are a terrorism problem that need to be reeducated or exterminated
-And you seemingly believe in an objective reality where the behavior of Omar (not to mention the rest of the squad) is a.o.k.
Human beings are really bad at objective realities. Watch Rashomon. It will enlighten.
