I am part of this generation. I have no answers to your questions. All I can do is feel ashamed and speculate.
My guess is that my generation is spoiled rotten. We never had any challenges or widespread hardships compared to the generations prior. Baby boomers dealt with Cold War. The Greatest Generation before them fought in World War 2. We got everything delivered to us on a silver platter, so we never learned to appreciate it or even learnt concepts of respect.
What the activists did in Peru is discusting beyond words. All I can do is hope that they are a horrible exception and that (Degenerate though as we are) the rest of this generation are not as bad as them.
