the tolerant left, right here on display for everyone.
I actually (as a left leaning Canadian) seek out conservative/libertarian/right-leaning news sources because I believe it's important to take in a wide variety of information, especially from sources which I might not agree with. There is a lot you can learn from anyone not on the extremes.
Not OP, but interested in right-leaning communities that aren't pants-on-head insane, just like I am interested in left-leaning communities with a similar constraint. /r/conservative generally isn't bad (I find they tend to be a LOT more level headed than /r/politics, for example) but things like /r/the_donald or whatever it was called is way too out there for my tastes.
