We are polite disagreeing, until someone comes and throw in our face that we can't because as fans, we only can agree... That starts the fire always. As it did now.
You cannot arrive as new to somewhere and say "hey, I don't like what you do", you first have to check that place and if you like it, stay in it and join the conversation, agreeing or disagreeing, but you never can tell anyone to change cause you don't like it...
