I understand why you'd say that, but the suggestion doesn't generalize. Even if we exclude articles like this one, there will still be many other articles with controversial and political overlap. Excluding them all isn't an option, and neither is allowing "ensuing partisan debate" to burn wild.

I wrote about this recently: https://news.ycombinator.com/item?id=20013092. If you read that and still think there's something I haven't addressed, I'd be curious to hear what it is.
