The hippies achieved many wondrous things..
Free love filled the orphanages.
Drug experimentation created a worldwide drug user epidemic including big Pharma.
Laws were rewritten to cater for the hippie movement in several areas, real estate being one example.
These hippies became the captains of industry, lawmakers and leaders of today's society which is not only disastrous, but could lead to the mass human extinction event
Yes the hippies were right, we should welcome them back, act irrationally and suffer the consequences later. IF THERE IS ANYONE LEFT
