"Communism" is an economic system. Every educated person knows that..
All one has to do to flout their ignorance in politics and economics the way a peacock waves his tail around is to call "communism" a political system.
Nothing demonstrates that someone is simply a carrier of megacorporation propaganda and has never thought for themselves or learned one whit about economics and politics as calling "communism" a political system.
And it just demonstrates that you believe what you want to believe without regard for the truth or reality. Demonstrates it very, very well.
It's not as if you haven't had the opportunity to learn, it's that you refuse to learn.
