Insults, haha! G@G has actually been a great learning tool for me, when it comes to learning how to deal with anti-fans better... and people, in general. I don't take nearly as many things personally as I used to, in real life too.
I'm never indifferent to anything. I merely measure up if I can do something about anything or not immaterial of receiving credit, criticism & stuff, if what I do / say will aid / help / have an effect or not. If not any of these then I don't bother with it. But I'd have analyzed anything crossing my path for sure but if I don't react or pro-act to it doesn't mean I'm indifferent. Likewise on GAG :)
