Too Much Freedom?

"Identity is never fully acquired, but is somewhat always incomplete, forever subject to modification." -Richard Troiden. 


This is a quote I just read in a psychological article about homosexuality. 
Aye.

I can't help but question a lot of things as I attempt to define my opinions on social issues from a cultural perspective. The main thing that keep coming to my mind is something is not right about our society's way of claiming truth. It is so interesting how one 'truth' to a social group can be lie to another. How have we gotten to this place where we have no definition for truth? It doesn't even make sense in my mind how people can even claim different truths to be ultimately true. Does that make sense to you? If we're talking about actual truth here, as in absolutely, undoubtably correct, there cannot be multiple opinions claiming truth. Why is there so much discrimination in our society? Because without an ultimate standard to hold our nation to (whether it be a moral standard,  a societal standard--derived from a moral standard, or some other guideline that I have failed to realize at this point), there will always be groups butting heads over which truth is actually correct. Because America was founded as a democratic nation, we are automatically doomed for discrimination. One group will essentially be the majority and will overpower a minority group automatically. Even if all groups are leveled out to equal playing fields, they will fail to agree on truth because there is no set standard to base truth upon. Each individual's truth is truth to them because it either a) makes the most logical sense to them; or b) is most convenient for their personal feelings.Basically, the way I see it, we are participating in a nationwide free-for-all. Right now, oh yeah, everyone pretty much digs it. Each can air their opinion and there is nothing stopping them from living how they want to live. This is America, for Pete's sake. Freedom. But what about in years to come? Like, when my kiddos are growing up someday. What will our nation be like then? It kind of appears that our country will be in mass mayhem because guidelines are being toss out the window more and more every year. 

I wonder what the line is that states a difference in having freedom and enjoying life in freedom, and having no standards to base our societal norms upon.
Also: what are standards? Where do they even come from? Obviously, they were conceived from some source. What is that source? Our constitution? Founding fathers? Well, they didn't establish the standard, they just followed one that was already set via their religious beliefs. We don't even follow the constitutional cores anymore, though. So we can't even base our standards upon that. 
Basically, I'm kind of stumped here. But I'm tired of listening to people state that it is okay to not have a set social guideline, because quite frankly I think that is a bunch of dung. If you disagree, I'd welcome your reasonings.
