FWIW I don't think it's pathetic at all, and I have the same reaction as you to a lot of things on HN. There are a wide variety of topics that bring out various biases and other cognitive blind spots in people, and bots.
Space travel seems to be one of the more harmless ones, but I agree it's frustrating to see people implicitly or explicitly skip over things like near-light-speed travel as solved problem, then reject arguments from others as "not thinking big enough", etc.
In general, divorce from reality doesn't seem to be related to intelligence at all in my experience. I'm sure there are plenty of times when my wishful thinking gets in the way too.
