The problem is we don't have the same enemies, there are people who claim to be left but oppose Liberals, such as Tankies. Tankies aren't the enemy of the GOP, they want the GOP to win over progressives like the DNC. They use words like "capitalism" to describe everything wrong with the USA because that way they can exclude the eastern dictatorships like Russia and China from the same criticisms.
Shit posts like the one above are the result of psyop campaigns.
