>I don't think "the right" is nearly as much of a trigger phrase as "the left".
I dunno, "the left" has their own terms to incite rage: far-right, white supremest (rarely any evidence), racist (same), right-winger, evangelicals, Nazi, deplorable, redneck, etc.
"The right" uses terms: liberal, socialist, communist, SJW, etc.
If you are strictly speaking in terms of which is more insightful and limit it to "the left" or "the right," I guess it depends on which circle you are closer to. I can see the argument for "the left" as being more insightful, but that might just be because of the circle I'm currently closer to.
I try to use terms such as those as a red flag. Anyone who tries to make a generalization for a spectrum as broad as "the left," or "the right," is trying to sell me something. I try to stick to policy, everything else is usually just theatre to distract from policy.
Somewhat related, Hillary Clinton was talking with BLM members about how to change things in 2015. She caught a lot of flack about it, but she was absolutely right when she said, "I don't believe you change hearts. You change laws, you change allocation of resources, you change the way systems operate." That's why I tend to stick to policy. Full disclosure, I don't particularly care for the Clintons.
