Because, they believed in something so profound and world changing that they deiced to fight to make it reality. Nowadays you can't get anyone up off their fat lazy arse without 3 energy drinks. Sure a lot of hippies did drugs. When you get into college, that kinda becomes the norm, everyone smokes pot, does pills, ect... at least once in their life. I look beyond the drugs and sex and see that they wanted a better world for everyone. But those with money liked were they were and decided to ******** things up good for everyone else. This is why we live in such shitty times. I hope in time, those hippie kids from back in the day can make a bit of difference.
