Horse shoe theory is just another word for “both sides” centrism and the people who are using it to demonize the left are the ones who MLK was referring to in the letters from Birmingham Jail. And plenty of these people will be quick to say they’re against far right ideology, but won’t do jack shit to support black lives matter, #metoo, fightfor15, unions, campus protests against fascists and colonialism, the prison abolition movement, or anti-war movements.
And plenty of these people here and elsewhere say they’re all for equality and shit, but will either never show up to support the causes or always have choice words about the methods in which these causes are strived towards. These people probably call themselves liberals or progressives, but are nothing more than diet conservatives who tell themselves that they care about women, the poor, black and brown lives, victims of imperialism and capitalism, but somehow they always prefer the status quo.
