More people have "fragile emotional states" these days because they've spent their lives being coddled and/or taught to respond to adversity by becoming a victim. When I was growing up bullies didn't say things on a website, they found you, beat your ass, then bragged about it to the whole school. Fortunately for me, my parents taught me that I was worth more than being some douches punching bag, and the important lesson that the only person who could control how I reacted to other people was me - besides, society isn't going to change because I'm having a hard time. Was it bad? Worse than most of the "whine about it on YouTube" generation could possibly imagine. Did I consider killing myself to end it all? Actually tried and failed a couple times to be honest.
But somehow I survived. Maybe its because I'm made of better stuff than other people, but that sounds. I ike self-aggrandizing bullshit to me. Rather, I believe it's because I realized that I was only a victim of my own self-loathing, and upon that realization learned how to have the confidence to stand up for myself in the face of, for lack of a better term, typical human dickishness.
Trolls (in the traditional sense), are easy enough to avoid - refuse to engage them and they'll eventually get bored and go bother someone else.
