There are other platforms for discussing Trump and his shenanigans. Reddit for example.
I vaguely remember checking one of those ICE posts out the other day, and there was not a single comment going against the grain that was neither flagged nor heavily downvoted, out of over a hundred. Nuance/dissent wasn't even vaguely on the cards.
I don't know what your definition of Reddit-like is, but that's mine.
So if the prevailing opinion is that ice is committing murder, it makes sense a contrary comment would be heavily down voted.
I agree that hn is heavily liberal and holds a lot of the toxic leftist anti-thought patterns that are prevalent on reddit. But I think it's more of a symptom of the country and perhaps the West being wound-up over "things".
