You might want to look up how certain political positions switched from being supported by both sides of the aisle to becoming wedge issues. Obama was most certainly not right of Nixon. That’s just absurd.

To get back to my question though, I don’t feel like you answered it clearly. Does your reply mean - since Obama was and still is very popular on reddit - that the site is center-right from your point of view? From a European perspective this might be the case, but not in the way the current American political spectrum is organized. The political spectrum is not an absolute thing, but instead applies to the current reality in a certain place and the relationship of its participants to one another.

There’s also the issue that people who are politically further away from the center perceiving those that are closer to it as more extreme than they actually are, e.g. a far-right person might consider a moderate to be far left and a moderately left-wing person might consider a centrist to be center-right.
