Comments and votes only represent the population of people who were compelled by interact and your view of the comments represents a selection of comments that are sorted by the majority's votes. Reddit-style comment sections tend to only lean one way, because the majority population pushes the majority opinions to the top (and the dissent to the bottom).

This meme is often used and demonstrates this (Survivorship Bias if you want to read on the topic)

That being said, if the argument is all one-sided then we have a comment section full of people who were so incensed by the comment in the OP that they felt compelled to respond to (allegedly) a Greenlander. Then the comments, I'd hazard to guess include some creative writing/LLM comments, are full of people attacking the ignorance of the statement.

So, what inspired those feelings of outrage if nobody is taking the other side of the conversation? Who created the conflict that made people write pages of angry comments addressed at Greenlanders? It wasn't a Greenlander, it was the OP.

The OP who also seems to leave these same kinds of little conversational bombs in various communities.
