that's a gross misunderstanding of the process of radicalization. people coming to political consciousness go where they see activity. they're not joining your communist party because you don't have a party to speak of. if you're a "leftist" who knows someone who has expressed genuine interest in radical politics and you see them get pulled back to reformism, social democracy, whatever, it's your responsibility to engage and push them further, and help them grapple with the contradictions between the establishment and their desires. conceptual obfuscation by that establishment is a threat, but it's only possible when we refuse to define the terms of our politics.
