I mean, the capitalists has a left, moderate, and a right, the middle class has a left, moderate and a right, the revolutionary left has a left, moderate, and a right. The conditions that determine these definitions vary from place to place and time to time.
Like I agree with the post, in one very narrow interpretation, but instead of insisting that one extremely broad abstraction is the "best one," which is a tendency we inherited from bourgeois hegemony and a misconception about how ideas spread, we should be helping each other to determine our own local conditions, how to be concrete and scientific about those determinations, and sharing those local conditions to develop regional -> national -> international perspectives. Only a mass party of and for the workers organized on the basis of objective human need and interest is capable of such coordination.
For example, many areas have organically progressive petty capitalist elements. During a period of mass struggle, like a general strike, the role of organizers is not to allow or even force those individual capitalists to side with the capitalists, but work with them to divide them from the right and moderate capitalists so they side with the workers. Is this deeply contradictory! Yes! But real conditions, especially revolutionary ones, are inherently contradictory.
I think its true that capitalism is right wing, that is, against progress. But is that actionable information? If applied crudely to actual struggle, it will create more confusion for people, than just like, getting people to talk to and work with each other and understand the objective conditions, so they can be changed and struggled with directly. Its too easy to intellectually transform capitalism = right wing into right wing = bad, and therefore individual capitalists = bad; which just leads to campism and sectarianism.
At this point, a left wing revolution will not destroy capitalism, it will transfer power from the minority capitalists to mass workers; and from there, continue to struggle on the basis of class toward another revolution that eliminates capitalism. Each revolution will be more humane than the one that came before, each counter revolution less severe. Getting engagement and agreement with a social media post or meme is completely different, and much much simpler, than getting engagement and agreement among the masses to initiate and defend a new phase of social order.
