As a lefty i think your examples are fair and worth bringing up. It seems folks assume because you pointed out intolerance on the left you must lean right and therefore you are downvoted?

The right has been radicalized imo beyond the left, but it’s fair to point out that the left has many examples (particularly on college campuses) of unjustifiable harmful intolerance. the idea that just the right has acted in ways that make people feel justified in their intolerance is narrow.

as op points out the intolerance on either side is not supported by The Paradox of Tolerance.
