SF is Right Wing?

I have never been a huge science fiction fan. I know that sounds weird coming from a guy who grew up reading tons of science fiction anthologies and magazines and novels. But it never made up a large percentage of what I consumed. Perhaps five percent of the fiction I was reading for most of my life has been sf.

In the past decade or so I began to read more of it. Again, it still was not making up a majority of what I was reading, but I had been picking up science fiction novels and anthologies more than in my youth.

And I was struck by something:

A lot of the science fiction I was reading, (and a lot of the science fiction fans I was meeting), are politically right wing. I'm not talking just a tad to the right. I mean full-on Libertarian Fascism. With the exception of Richard K. Morgan, most of the speculative fiction I was discovering is, it seems, being written by people with right wing extremist motives and sympathies.

Has this always been the case?

Yes, I know that shit-hole Robert Heinlein has always been a darling of sf fandom. And I used to encounter right wing creeps on most of the sf-oriented chatrooms back in the early days of the Internet.  For instance, when I tried to interact with Bradbury fans to get information I needed for a project I discovered that they were almost all politically to the right and eager to bombard the Internet with their poisonous dogma. (This should not have surprised me terribly because I already knew that Bradbury had obviously gone from a politically progressive young man to a right wing shithead by his later years.)

But is the majority of the modern science fiction literary scene infected with right wing mania?

I do know that I have quickly grown sick of trying to read these Libertarian/religious/Objectivist/Fascist screeds in the form of science fiction novels and stories. I've reached a point where I'm prepared to swear it all off and go back to reading non-fiction to get away from the endless drone of science-fiction's neo-Fascist themes.

Alas!

Is all modern SF nothing but Fascistic shite?
