assuming not satirical...those people opposing socialism have led it to shit for those decades, to a point where the propaganda can no longer hold the illusion that right-wing politics are for the people. The trouble is that the USA only has a far-right party and a centre-right party, so socialists won't get much representation unless they're willing to start something new. The DSA wing is a decent start.

We tell them by creating massive anti-socialist propaganda campaigns, running them out of the country by destroying their livelihoods, and then going around the world mass murdering leftists. Anyone who think socialism is gaining a foot hold is bonkers. The US would gladly nuke itself to stop it without thinking twice.
