I love to argue
And reddit is the perfect place because it's anonymous and everyone has a take. In order to strengthen my views, I need to duke it out with other people. Either I feel more confident that I was originally right, or it turns out i am wrong on at least one aspect, and I can update my world view. Its a win win.
I will still try to defend an idea if someone blows a chunk in it, like a little boat that i am riding to shore. I will still try to win that argument with the original premise unless its obvious that its just wrong, and then I will easily admit i was wrong. But its better if the battle is murky and I can quietly update my view with a new little trinket.
My friends and family do not love to argue. They do not see building a useless kingdom of knowledge as important, and they often cannot separate belief and identity.
For me, I will happily shed layers of identity if it means I am getting closer to a correct and comprehensive world view.
