Clearly, you're fine putting words in other people's mouths and making subjective claims about the nature of one's post.

You're fine rejecting my arguments for why his post is arrogant, but somehow yours about why my post is condescending are valid.

That's a toxic and arrogant way of arguing, so I'm not surprised you're projecting something I didn't say. Honestly I would have expected better from an HN audience, but techies are still people...

Also quite indicative of what would happen on Mars.

I'm not putting words in your mouth. Direct quotes: "No offense, but you sound like a person who hasn't been outdoors a lot, not even on an overnight hike." and "That should hopefully rid you of the naivete and hubris about space frontierism."
