Every single large server in this federation has at least one Star Trek community. There is even an entire server dedicated to Star Trek.
Not only that, these communities are some of the most active I’ve ever seen. There is no other franchise I know of that dominates the federation as much as Star Trek does.
So, what’s the correlation with Lemmy and Star Trek? Why not other sci-fi series? Please, are there any connections?? Is this all coincidental?
In my experience it is a very very loose collection of ideologies that share the common idea that there is no innate hierarchy between people and that helping others does not necessarily erode your own place in society.
Edit: Oh, it was an ELI5, then a leftist is someone who thinks other people in their sandbox does not make the sandbox worse.
