That's fine if they don't want to explain their statements. It's just frustrating when I ask for an explanation and get downvoted for asking.
Maybe I'm just posting really unpopular stuff recently, because I've noticed 2-3x the downvotes without explanations the past week as compared to normal.
Unfortunately on HN, some won't give a reason, explanation or any evidence of the details you are asking for.
Claims are left without any substance and are left to you or someone else to refute them. Leaving everyone confused.
What a shame to a discussion.
