What does it mean to be communist?

The right usually defines communism in one of 2 ways:

1. The economic opposite of capitalism.  This means they don't want well off people being forced to subsidize less well off people.

2. The free speech opposite of the first amendment.

With this definition, then the Catalonian independence movement would have no communist backing.  They are the ones who get censored by the Spanish government in protests and the rich Catalonian province (by the standards of Spain) subsidizes the rest of the country.  So you figure the Catalonian independence movement would be a right wing movement; but it turns out to be a left wing movement, therefore communists are more likely to back it.

How did this happen?

Contrary to what right wingers think, Communism is an extreme form of both political and economic Democracy where businesses and political institutions are run in the most decentralized and collectivist way possible. The goal of Communism is to destroy all forms of hierarchy in society.

The right winger typically confuses any country that has a leading political party that claims to be "Communist" with Communism itself. According to Marx, various stages of Socialism are necessary before Communism can be achieved so even countries that have been run by genuine Communists are not Communist countries. 

Just so you know I'm at the point that I'm just going to stop reading threads you create. You keep doing the same insane things. You setup an absurd definition, then you equivocate that definition based on the words (no seriously look up the equivocation fallacy), then you ask profoundly stupid questions about why people who don't give a shit about your absurd definition don't politically align with the contradictory worldview you've setup.

It's like the same bullshit that happens when people go "Nazis can't be socialists because they fought communists" except 10x worse because there isn't even an appreciable number of people who accept your definitions for words.

Said nobody.

At least when you say nazis are socialists or communists are socialist, there were millions of people who called themselves both nazis and socialists and both communists and socialists AND STILL they killed each other by the millions.

Your concept of the world is utterly useless because you (apparently) continue to believe in this thing "the universal right-left paradigm"

There is no "eternal right" there is no "eternal left" there is no assignment of philosophy or belief that will EVER allow you to understand the world as the interplay of only two worldviews.

The number of sides = 2 comes from one place and one place alone: strength in numbers. Two is the minimum number of sides to fight so when every alliance that can be formed (and still fight) there are two sides left.

That's it.

You may as well be asking of Genghis Khan was right or left wing. ENOUGH! It's just a seating arrangement.

Then I won't read the rest of your post.  Simple as that.

This is the same as my first bullet point.  Capitalism is individualistic; communism is collectivized; and racism is a subset of collectivism; treating people by their group rather than them as individuals.

You have it backwards, racism creates hierarchy and the more left wing you are the more you value equality. Putting one race above or under another is a very right wing thing to do.

Valuing a human being over a chicken creates hierarchy; it doesn't mean communists want to try Chick Fil A eaters with a murder charge.

It is right wing, but it is also collectivist.  Right wing and collectivist aren't interchangeable nor mutually exclusive.  The least collectivized ideology is American style libertarianism.
