You are misinterpreting me. Take for example, your right to bear arms. It is an important freedom but it can also be used to deny others freedom. You can deny someone their right to live with it. You could also enslave someone with it and force them to support you with their work (the exact same thing you are complaining about). You can say how you think things should be but at the end of the day we have to deal with reality. Reality is that if enough people want to force you to follow their rules, you will never achieve that life you are hoping for.
If you have a better system please let me know.
The government is not one thing that represents one view. It is a conglomeration of many different views. If you don't feel your opinion is represented it's probably just because it is getting drown out by the other 300,000,000+ views. Your rights are not borrowed from the government but your rights don't always enforce themselves either.
The word allow is confusing things here. A grill "allows" you to grill a steak. It doesn't give you permission. When I say the government allows us to determine our freedoms, I mean government is only a tool through which citizens can collectively decide and enforce those freedoms. It's still the citizens deciding, not the government as some separate entity. Also, freedoms may not last long if you don't have any way to enforce them. Of course governments are just as capable at taking away freedoms as it is protecting them. There is no solution to that problem that I know of. Checks and balances are the best we have.
Very true, but God and nature do not enforce those freedoms.
The constitution was and still is that agreement. The founding fathers were not dictators, they provided us a method to change the constitution. If enough citizens disagreed with the first amendment, it could be repealed through our constitutional process. The fact no one is trying to do that is reflective of our ongoing agreement.
I think some people are too caught up on the difference between a democracy and republic. The central issue in this discussion which you mention is that there is a process for the constitution to be changed. Thus there is no rule that isn't subjected to the citizens will. True, our republic requires more than 51% to change it but the core principle of collective agreement remains.
