If there was a point to my fist-waving it would be that there's no such thing as knee-jerk assurance when it comes to security. Yes, HTTPS is a good sane default in probably 99% of situations, but that's because the distribution of privacy-requiring contexts on the Web such as shopping and banking is disproportionate to the average.
