Isn’t the worst socialism still better than the best capitalism? Why try to destroy “revisionist” socialism when you have capitalism to destroy? Wouldn’t it be easier to fix a revisionist socialist country than trying to convince a capitalist one to be socialist?
Revisionist aren’t “bad” socialists, they are Liberals. What makes an idea revisionist is if it will reverse the progress of socialism and reinstate liberalism. Revisionists are more dangerous than liberals because they twist socialist language and ideas into supporting liberalism. They have negative revolutionary potential.
