Your horseshoe theory is not a nuanced theory. The position that bigotry runs on all sides is not a nuanced position to take. On the contrary, it states an absolute and generalizes over non-generic things. What you call left-wing bigotry is only bigotry in your mind, as you want to draw a false equivalence. Furthermore you seem to fail to realize the paradox of tolerance—that you cannot tolerate intolerance while maintaining tolerance of everything else (do you realize the nuance yet?)

Lets start with a true statement of yours:

> Almost all Americans don't like racism.

This is a true fact. However it says nothing about systemic racism, or racist cops, or racist politicians. Me being a left-wing bigot would state that the latter is bad and should be abolished, and might make a statement like: “Anyone working against the abolition of systemic racism is part of the problem.” You will probably say this is a bigoted statement, and deserves the same scrutiny and moderation as those who claim we should further systemic racism, and state something like “Cops are justified in policing black majority neighborhoods harder than other neighborhoods”.

This falls into the paradox of tolerance. See if you disallow both our speeches, as they are equally bigoted, you are favoring the status quo, and if systemic racism does indeed exist, you are tolerating it’s continued existence. This is where your horseshoe theory fails. Reality is much more like a fishhook theory. Where the centrist take will always be closer to the far right.

I’ve been playing into your rhetoric, but just so you know, you cannot call anti-fascism bigoted without finding your self in a paradox. A slave owner that hates their slaves is an abuse, a slave that hates their master is liberation.
