The fatalistic attitude exhibited in some quarters of public opinion seriously worries me. There is being realistic but trying to change things anyway, and then there is being fatalistic and not bothering to even try. As a species, we'd long ago have ceased to advance if we took the second option.
I also find the penchant for blaming violent games etc to be infuriating. It's a cop out. Overly simple. Most of all, I find the idea that anyone who enjoys such things is evil and or disturbed to be insulting. I partake in such things but I also possess the mental capacity to create a sensible moral compass that guides my actions in the real world, as do the vast majority of people who consume such media. A tiny minority is portrayed as the majority and it drives me crazy.
I have staunch opinions on a lot of relevant topics to the terrible events that took place, but I won't state any more here.
