Hell, depending on who you ask, bullying isn't even a trigger.

After all, most of the MTV generation (and a fair number of their kids) grew up with the mindset that "if you can't fight back, expect your childhood to be hell". Sugarcoating the world for kids has, in turn, reduced their resistance to how shitty life gets, meaning that the same bullying that parents had to deal with is now driving more and more kids to suicide and homicide.

Yes, again, I just went there. I believe moral guardians are partially at fault for bullying being as big of an issue as it is nowdays.
