That's a good and reasonable personal ethic, but it transfers into a (imo) poor, even disingenuous public discourse.

Let's say we're talking about the clickbait/trolling problem in political discourse. We can berate some prominent individual, but that individual is inevitable. If she wasn't doing the clickbait, someone else would be and we'd be beratying them.

Focusing on the individual when a problem is systemic can be empty, righteous moralising.
