How do you know that they will never change? Because it's always been like this? Because three thousand years ago everything was exactly like today because nothing ever changes?
I understood perfectly well what you said, I just inherently disagree with such a meek and defeatist statement. I will stand up for my beliefs whether people like it or not and if enough people do it, things WILL change. It's happened before, it's happening now, it will happen again. Change is always possible with the right attitude.
