I also get the impression that this forum is pretty far to the right.
Pretty far to the right
relative to what would be the key question, as you say it's a matter of a perspective.
For example, take the media bias chart (which is accurate enough for this in terms of the left/right scale, the Y axis is a lost cause):
People tend to assume thier position is the same, reasonable, obvious position, because of course it is, if it wasn't the sane position then they wouldn't hold it, and they define the spectrum in those terms, not in terms of the objective center. And they understand their neighbors on that spectrum much better when compared to the farther reaches. I can explain the difference between the National Review, Fox, Daily Caller, Reason, and the Federalist pretty well, and then on the left wing side I have a mental boxs labeled "liars" and "dirty commie liars" and sort thrm.in one of the two*.
Mapping forums onto this chart:
I would put the average discourse as somewhere in the "The Blaze" or "Daily Caller" range, solidly right wing and opinionated, but mostly based on facts or principles.
SB is somewhere in the Daily Kos range, which is more based on feelings and opinions and then you grab facts to back them up.
SV isn't on here, because I guess Pravda was so far left it didn't fit on the chart.
*This is a joke, but only just (there's only one box).
