I'm personally a pretty hardcore leftist, and from this position both liberalism and conservatism are too right leaning for me. Of course the democrats are closer to me, but I think it's important to keep in mind they are conservative lite, not truly left leaning. Establishment Dems in particular do not have the best interests in the people in mind, similar to Republicans. "Both sides" are acting to preserve capitalism and consolidate power, not distribute it.
With that in mind, the typical "both sides" argument that there's extremists on both sides is ludicrous to me. Extreme leftism doesn't mean forgiving student debt or implementing a UBI, it's banning corporations in lieu of co-ops, or replacing any company that provides things we need to survive with state-run monopolies (like single payer healthcare, for example). Neither side is left enough, and rhetoric that there's a happy medium between the two parties will end with us being incredibly right leaning.
