why are people so hateful towards communists?

I am an marxist communist and have received alot of slander due to my political beliefs like RED, Commie bitch, Lefty and better listen to your master and shhhh and other stupid shit seriously being a leftist is no worse then any other politics so where does all this unfounded anger stem from? and why?

Communists believe that it is the people or proletariat that controls the means of production not the government or bourgeoisie thats in Marxist doctrine
