Technically, Hitler was a fascist (the term "socialist" in the Nazi party's full name was mostly an artifact title by the timehitler rose to power) and all the others were Communists, but I guess they're similar enough...

Read up on Marxism.

I said similar enough.

Contrary to what you seem to believe, there actually is a difference.

Contrary to what you seem to think I believe, it isn't that much of a difference.

Also, contrary to what you seem to think, I do not support socialism, as it is a disastrous economic system that is almost as bad as communism.

P.S. I know you didn't make this meme, but for future reference, gun control belongs on the authoritarian-libertarian axis, not the conservative-liberal axis (communism and fascism on the other hand)...

You forgot to add another name to that list.
