I think Soviet style communism is dead, except in places like North Korea. What we have now are Marxists who masquerade as Globalists (UN types) and even Capitalists. In many ways, the Soviets were easier to fight ‘cause you saw them coming a mile away. The current crop are shape shifters and can burrow deep into any organization.
Communism means the same thing it’s always meant. Phonetically, the word gives the ideology what it deserves, because it sounds at the same time dim-witted and nasty. Maybe this is one of the reasons the communists tried to kill the word.
I was very pleased when Trump use the word communism during the campaign. It shows he’s never been susceptible to communistic propaganda.
