I have been a part of academia for the last 20 years and I can tell you that it has changed a lot just during that time. Neo-Marxism and enthusiastic leftism is not viewed as ONE point of view in the curriculum, it has become the ONLY point of view and it is the curriculum.
Pet topics like: gender constructivism, feminism, class warfare, anti-capitalism, white privilege, and others are now central to all areas of study in most modern N. American colleges (even for subjects where these topics are ill-placed such as the pure sciences). Anyone pursuing post-doctoral studies is practically required to touch upon one or more of these if they wish to have any hope of succeeding. If these topics are not dominant in the curriculum, or if opposing viewpoints are permitted, untenured faculty runs the risk of losing their postings. Students wishing to engage in dissenting views are smacked down and their grades suffer for it. This is happening right now. I have witnessed it personally in a prestigious university. Check out the film Indoctrinate U.
The hippies who championed the right to dissent have become the establishment and have unfortunately adopted the same parochial practices as their one-time opponents. They are going to make this world a kinder and better place according to their own standards no matter what anyone else thinks. For now, this seems not to have become as pervasive in government as it has in academia.
I am not saying that their positions should be silenced, I am simply saying that theirs is not the only valid position. As soon as people en masse start believing that they have any moral authority, bad things happen. As a student of history, you have surely come across many examples of this.
Why should a store be permitted to dictate to people how they should express their holiday sentiments. Do Jews, Muslims, and other non-Christians really get offended if someone wishes them a Merry Christmas? Perhaps atheists do, but then why should they care?
I am sure that there are many hippies that were veterans, but let's be frank here, the vast majority of them burnt their cards and skipped out. I probably would have done the same thing, but you see, I would have been more honest about it. I would have dodged the draft to save my own ass from being shot up and would not have claimed to be taking some moral high ground.
Tolerating dissent is key and it is well represented in The Way to Eden. Even though Kirk questions the Space Hippies' morality, sanity, and politics, he still allows Spock to help them try to chart Eden.
