I am really surprised by the HN community. I wasn't expecting people to downvote an user who politely expressed his point of view just because theirs is the opposite.
You shouldn't be surprised. There've been plenty of examples of people stating facts germane to the topic and nevertheless downvoted because some folk don't like that fact being referenced. Be nice if they had to offer a reason for their downvote. Quite a lot of bigotry around.
