Totally agree. There are many things that I don't like, for example in this fandom too, but I won't comment or criticize it just cuz I have rejective thoughts about it, especially when it's tagged and you were warned what you are reading. On the other hand I can understand why you feel the urge to give air to your opinion. If there is something I feel that is not decent, adoptable or proper I put on my debating mask, collect the reasons why I don't agree with it and debate the s*** out of the topic. Now, that's what I try to hold back for example when I'm here. I know that there are as many opinions as people so there are many things I see inappropriate still other people's point of view can be acceptable too or even I'm the one who doesn't get the point.
I support this idea, can be a way.
Well if you criticize something that other's like you should prepare yourself to be criticize too. People usually have the sense of a lioness which tries to protect her cubs and if you have cubs too, they will do their best to reach the same effect even if it's not a proper method.
