Well, my take on this is that you can't fight the system. But you can change system.
There are numerous books on change management in business, and most of them conclude that it's a lot easier to start a new company than to change an existing company culture. That is, unless the change is trivial (by various definitions of trivial).
Likewise I think you are better of finding more free minded people. You can burn yourself out trying to convince a single conservative person. And the alternative is that you find peers where you can share your experiences freely and spend you energy on your own voyage, not on the acceptance of it by your dissaproving surroundings.
By this I don't mean that you have to stop seeing these sceptics, just that you choose what you tell them. You have to adapt to your surroundings.
Of course it sucks to realize that you cannot truly be yourself in a certain group, but I think that is a sad truth that lurks in our society today. There is a reason why so many alternative thinkers flock to big cities.
I definitely don't believe that you are the only one feeling like this. Most likely there are many in your surroundings. But people put their needs aside to conform to the social group, and that is what they expect from you too to stay a member. If you don't want to live that life, you have to break free.
I wish you the best of luck!
