I used to be a leftist and I would address issues under the capitalist system such as homelessness and people suffering in poverty due to their jobs not paying them a livable wage and high rent and I would get harassed by libertarian/ancap trolls, they would call me all sorts of horrible things such as "communist", "socialist thief", "Marx", "Stalin", "economically illiterate" and "retarded". Libertarian trolls can be just as bad as leftist SJWs who call everyone to the left of Karl Marx a "Nazi", "Fascist", "Hitler", etc.
