I like arguing online. I like disagreeing with everyone. I disagree with Liberals on Identity Politics and Censorship. I disagree with Conservatives on Social Darwinism and support of guns. I disagree therefore I am.
Perhaps I have never changed anyone's mind. But at least reading other's outrageous opinions and arguing against them gives me Adrenaline. It gives me more Adrenaline then playing Runescape.
Perhaps arguing is a harmful habit. But the health damage is an order of magnitude less then damage done by Alcohol, Tobacco, and illegal drugs.
