There are plenty of folks on the actual left that support gun ownership. I support gun ownership because (1) I do not believe that I should not be armed for self-defense when the exact types of people you mention (fascists, racists, etc.) are armed; If the far-right is going to arm itself and use those arms against the far-left (which would be a given in any revolutionary crisis or situation), then I'm going to arm myself and defend myself against them, and I would hope that my comrades on the far-left would do the same.
Individual pro-gun fanatics don't have any balls. These people constantly post of FreeRepublic and the like about CWII and RAHOWA, but every single time one of them actually acts upon that propaganda, they retreat inward and start screaming about Obama false flags and crisis actors or whatever. Mass leftist revolt is their greatest nightmare; if that ever happens, all they'll do is cower under their bedcovers, occasionally posting upon Freep about how they totally shot 50 commies.
This is laughable for the exact same reason right-wing lunacy about guns being the final defense against liberal tyranny is. You are trying to rise up against the most powerful armed forces on the planet. They have tanks, planes, drones, EVERYTHING. Pea-shooters and old rifles will not save you here.
You are going to lose. Yes, but in the meantime, Trayvon Martin, the Sandy Hook kids, and countless other victims are still very much dead, and the inevitability of the glorious socialist revolution (which we swear is going to happen any day now, really) isn't much comfort when the families of the aforementioned victims know it's still very much possible for more atrocities in the same vein to be committed.
