Which, I assure you, makes him the rare exception rather than the rule.
Using someone unnecessarily peppering insults into all their responses to people who disagree them as a "rare example of someone who cares" is an odd choice.
They don't care enough to be civil with people they disagree with and even they can be altruistic. How much more altruistic can we expect all the people who don't insult everyone who disagrees with them to be?
