Except for one or two, that were definitely against HN guidelines, you’re right. Most of the comments were downvoted because of opinions. It was used as a “I disagree” not as a “this is disrespectful, not adding to the conversation, not factually correct (4 == 3). I try to only downvote in those situations.

I will flag any submission that I see is over political even one that I agree with. Politics and religion topics rarely lead to intellectually stimulating discussion.
