The first two points are fine, obvious even. Although they are not a satisfying answers to the questions "Why are authoritarian ideologies becoming more popular?" These answers seem equivalent to answering a physics question with "we live in a strange world" and then just leaving it at that.

The latter 2 points are bothersome. I much prefer the default "social contract" implied by most messages: "These are my thoughts. I welcome further thoughts or counter arguments. I may or may not participate in further discussion." That goes without saying and seems much nicer than "I'm smart and my arguments are sound, but don't expect further discussion, see ya".

There's an interesting discussion to be had around point 2 and the pros and cons of different ideologies. All of that was buried beneath points 3 and 4, asserting your intelligence and discouraging further discussion.
