The tooltip for a question comment reads:
Use comments to ask for more information or suggest improvements. Avoid answering questions in comments.
The tooltip for an answer comment reads:
Use comments to ask for more information or suggest improvements. Avoid comments like "+1" or "thanks".
The wording of these tooltips makes more sense for computer programming than than it does for politics.
To a commentator favoring one spot on the political spectrum, "suggest improvements" often seems to imply, and is therefore inferred to mean, that they should help by extolling the norms and virtues of their preferred spot, or by condemning those spots occupied by that particular question or answer. Since the commentator is only helping a misguided person who seems lost, such extolling and condemnation often seems, to them, compliant with the "Be Nice" policy.
How does a user "improve" a wrong answer? Or an answer that seems to them, given their orientation, wrong? Is the verb "improve" ill-suited to political discussion?
