The left dominated media and culture as a result of that.

Do you even know what “the left” is? It’s not liberals; it’s not Democrats; it’s socialists, who want to abolish private ownership of the means of production. And we have never dominated the media, because the media are owned by the bourgeoisie. We won’t dominate the media until after a socialist revolution, when the proletariat own the media.

The Democratic and Republican parties are both objectively right-wing parties. They’re both pro-capitalist/anti-socialist parties.
