The only difference is, at least in my experience, many hippies don't actually do the things necessary to create change. They are individuals touting a known consensus. It's the reason why green measures generally fail in politics but stupid things like protecting the second amendment are upheld strongly. There is no centralized institution to fight for these beliefs. This is why you see the Freedom From Religion Foundation actively fighting against many religious bills. It has a goal, the ability to garner funds, and a means to support people to achieve them. Most hippies are just getting by and eventually wake up realizing they need a job to survive once the donations wear out because they don't have a stable supply of people believing in their individual cause.
