How do we refocus our efforts on recovering individual liberty in the USA?

I took this photo at Seattle Pride yesterday. Political equality issues aside, I think this demonstrates a level of individual​ liberty that we should strive for in the US. Not just on specific days, but everyday. If you look close, you'll see all types of people - black, white, Asian, other; children, parents, youth, workforce and retired; gay, straight, trans, bi, and everything in between; rich, poor, middle-class, unemployed, government workers, business owners; clothed, nude, sparkle painted, puppy masked; all aspects of humanity are represented in this picture. All of these people, getting along, having a good time, being who they want to be.

This is individual liberty. This is what we should be striving for - for everyone, everyday. How do we get there from where we are today?
