There's a fairly non-specific, second-hand example regarding a student which made complaints with an unspecified basis about offensive writings of Mark Twain and Edward Said that preceded the non-renewal of a (different) adjunct professor's contract, which the author relates resulted in the author expunging anything they thought might be perceived as offensive from their syllabus (the author doesn't explain how they "saw" this scenario unfold, and given the usual confidential nature of such contracting decisions, it seems unlikely as someone who was neither the subject nor the decision-maker that the author had the full picture of the discussions or the reason for the decision.)
Everything else is the description of the author's fears about what might happen, and repeating non-specific generalities from other sources.
So, there is one vague subsequent example, but nothing in it actually specifies the basis of the offense and ties it into anything left/liberal (or right/conservative, for that matter). I've seen both left- and right-origin complaints about both Twain and Said (in the latter case, often the exact same complaint, of his perceived-by-some anti-Semitism.)
