If you're a self-described moderate, there's something you will notice when you sit down to consider the media put out by reactionaries, versus the media put out by the radical left.
Reactionary content is blatantly harmful. It provokes fear, either directly or indirectly encourages hatred, and support of hateful and damaging people. It's what their ideology (or, technically, lack thereof) is built on.
Radical progressive, #
communist, etc. content may offend your sensibilities — did that person really just say "Stalin did nothing wrong"? — but it isn't
dangerous. You might think I'm completely out of my mind for my support of North Korea, but that isn't hurting people: Even if you fully believe that the DPRK is imprisoning and torturing its citizens en masse, my support for the 'regime' couldn't possibly make that any better or any worse. The most I could do is convince you that that isn't the truth, and redirect your outrage onto more pressing (and real) matters — onto creating a better world by caring about people.
So while I may inspire the same kinds of feelings in you as a fascist might, if you're a centrist, that's where the similarities end: I think we should forcibly depose our capitalist oligarchs. They think that we should defend those capitalist oligarchs (via the system they have created) to the death — that is, the death of all the minorities they fear and hate. It won't hurt you, or anyone else, to read with your eyes what I have to say, or even share my media, even if you vehemently disagree with it; but sharing reactionary media does direct and measurable harm — unless you count the bottom line of a billionaire.
