I think most people don't want to stir to the pot so they take themselves out of the equation. I'm not saying it's right, but that's my interpretation. I used to defend characters more frequently myself but realized the trolls don't stop. And honestly, it got too exhausting. I only participate in mature discussions now. I'm all for differing opinions (praise God the world isn't made up of a bunch of clones) if each party remains civil, but otherwise count me out. lol.
