I have to point out that communism is the opposite of fascism
Sorry to disappoint you, but they
are not. They're basically the very same thing with a different name.
Prior to talk of left and right and use meaningless graphics, where the only point is "they're left because they call themselves that way", you need to know and define exactly what those sides are and what they stand for.
On the beginning it was easy, Jacobins and Girondins, Jacobins sit on the left side of the French parliament (hence the name) and Girondins on the right. Jacobins were radical and wanted to eradicate all wealthy persons, Girondins were moderated and seek understanding of the French classes. So on the beginning it just means radical (left) or moderated (right).
No need to say, a couple of centuries later, when communism showed up, there was already nobody on the "left", so they took the empty spot and are marketing it ever since.
So what it means now?
As the communists got to be the "owners of the left" (it should have a TM after it) basically you're "left" if they say so. Nazis were... until 1942, then they suddenly got to "extreme-right", was more of a "copyright violation" than a political sphere movement.
On the political compass left and right are separated by own much the state controls the economy; from "all of it" (extreme-left) to "nothing at all" (extreme-right). On this compass, Fascism, Nazism, Communism are close neighbors, on all of them the state has full control over the economy. On the other axis that goes with your individual freedom, they're also on the Authoritarian side.
So, as you see, you're just reacting to marketing about the very same product. In philosophy when
you do the same, you're the same.
As a footnote, a North Korean girl if get pregnant from a foreigner will be forced to abort; they're extremely racist.
EDIT: This is how "antifa" reacts to Hitler's speeches when they don't know the author btw:
