I have no idea how this screenshot illustrates your point but there is an “alt-left”… sort of. This term is not really used though. The term “alt-right” was used to describe far-right elements of the American population whose ideology was regarded to be extreme enough that mainstream centre-right politicians wanted nothing to do with them. “Alt-right” is (was) essentially a polite euphemism for right-wing extremism.
If you want, you could consider the left-wing version of this to be the socialist and communist groups, but they are politically irrelevant in the US, not only because the centre-left absolutely refuses to even acknowledge their existence but because the “alt-left” also hates the centre-left and isn’t willing to co-operate with them to get into power. The “alt-right” holds political sway only because the centre-right realised they were useful in riling up the right-wing voter base and they could be used to get into power. Unfortunately, this really just meant that the centre-right has disappeared in America and been replaced with only alt-right or alt-right-sympathetic politicians. The “alt-left” of America is completely unrepresented in any institution of government. Again, I want to make clear that “alt-left” is not a term that is in widespread use but if you generalise the prefix “alt-”, it’s what it would mean.
