One of my contrarian opinions (judging from the number of comments here) is that it is best to avoid posting controversial contrarian opinions on social media, including HN, in response to a question (e.g. Ask HN) especially if the OP asking the question is not a well established user. The OP could be a troll or maybe employed by a government looking for people that should be surveilled. To be honest though, it is thought provoking to skim though all of these out of the ordinary ideas and responses.
