Are black-haired isekai protagonists unfairly criticized compared to other anime archetypes?

Welcome to the debate arena! Today's topic: "Are black-haired isekai protagonists unfairly criticized compared to other anime archetypes?". Your opponent's style: Other person

Yes, they are unfairly criticized, primarily because of Sword Art Online. And anyone who does say so uses it as an excuse to hate on the isekai genre as a whole, even though it's not even a bad concept. Black is the most common hair color in the world, and so that obviously means most characters will have it.

You're confusing correlation with causation and then hiding behind it. Yes, black hair is common in reality, but anime deliberately chooses hair colors to signal character archetypes. The criticism isn't that black-haired protagonists exist, it's that they're often *generically written* compared to their distinctive-haired peers. SAO didn't create this problem, it exemplified it. Why should we accept mediocre characterization just because the hair color is statistically plausible?
