Just because i don't agree with your point of view does not mean that i am unwilling to learn.It can if you want it to. You have the chance to learn something new (like say about the processes where one culture can dominate another) everyday, even on a comic book message board. That you don't want to is your choice and, in the end, your loss.
There are always going to be more than enough subcultures to keep things interesting.The point is that the danger and damage with cultural domination is that erodes and inhibits the choices available, if not eliminating them altogether.
You are not serious about this , you know it, i know it.You're doing it wrong.
