Just to clarify, I'm definitely not trying to suggest that this is the only reason you should be respectful. This is more a message about people within tech, who are numerous, that get frustrated with working with other people due to actual or perceived incompetence. The parent comment mentioned the 'it's ok to be an asshole if you're right' myth, which is particularly prominent in software projects or in tech related discussions. I would deduce that the only reason that smart, capable people do not invest the time or the energy into moderating their tone and choosing their words is because they don't see value in it. My point is that there is empirical value in it even if you're purely seeing it as a means to an ends.

Absolutely the rest of us who are just nice and pleasant as part of our day to day should continue to do so, we just need to remember that their isn't really a justification for ad hominem attacks as part of professional discourse.
