That's like the classic of saying "no offense" after you realise it was actually a obviously offensive thing to say. It doesn't change anything and is a semantically meaningless statement, and you still were offensive.
I dislike how HN'ers attach meaningless disclaimers like these at the end of every sentence they make because they're so afraid of getting downvoted. It just goes to show how much damage over-moderation, echo-chambers, and such things make to honest and legitimate discourse.
If you want to make a statement at least own it.
