Too many Rights?

Everyday there's another person preaching about how, "The government is taking away our right to do this." The real worry, to me, is why is it that everything is automatically a right? Better yet what is a right?
The basic definition of a right is an undeniable principle, concept, or freedom, that cannot be legitimately be taken, unless by an act of power. Now, how to figure what rights are... well, actually rights.
For the most part, the "rights" that many people swear by, often are not rights. Example, the "right" to smoke. Nowhere, anywhere, is there a protection of the ability to smoke tobacco. Yet, people would fight that they have the right to smoke, while on the other side of the aisle people will claim it's their right to not be bothered by the horrible smell, and health consequences of second hand smoke. Although many people say that America is a land of freedom, and believe in turn, that this freedom means they can do whatever, is very contradictory to the actual practice of freedom within the U.S.
John Locke's Social Contract outlines the basis of America's relationship with freedom and civil liberties, as anyone who took History in High School can tell you. Even in The Federalist Papers Alexander Hamilton, and James Madison talk about how Americans can enjoy a free society, only by agreeing to keep freedoms inside of limitations, being that infringing on other's rights means that it's a free society for you, but not for them. For example, I feel compelled to have some unpaid workers work in my greenhouse. They work for me as I demand, do what I tell them, and follow my every command. This means that there is a free society for me, but for my workers they are oppressed by me and therefore not free. This obviously is a more modern version of slavery which has long been illegal for the very reason that it creates a split society.
Now, the question is to what extent can this go? Can I fight against stores because they infringe on my freedom to eat food I can easily find in nature? Can I fight against teachers for making me read boring books, and infringe on my right to not be bored to death? There has to be a fine line drawn as to what rights can, and cannot be slightly stepped on for the sake of Freedom and Liberty. This means people can publicly preach passages from The Bible without me being able to stop them simply because I don't agree with them, and this offends me. Of course, there are grey areas, Smoking, Guns, and many other fought on subjects.

To finish off this post, I would like to address the common fight against Gay marriage, and Abortion. Many people claim that these should not be allowed because it is against their morality. As I explained in the post, and shall expand upon, just because someone thinks/acts/believes differently than you, doesn't mean that you can simply say that they are wrong, and restrict their rights to practice what they believe. I'm not justifying Abortion on the grounds that someone is "naughty", but just because one (two in this case) religion says that something is wrong, and the people use their morality as a reason to constrict the rights, doesn't mean that they actually can. In fact, this is wrong on so many levels. Morality is not a justification for oppression, or the suppression of a people's rights, and liberties to be free, and live as they see fit. So long as there is not physical harm, obstruction of the public, or breaking of the law, a right can be freely and openly practiced. This means that, although you cannot yell FIRE in a theater, or smoke marijuana in protest of prohibition, you can express your religious viewpoints, or be gay as you wish. This often gets mixed up and confused throughout the public. So hopefully I taught you how to better interpret rights, and freedoms, though all laws, and rights are fully open to interpretation from all.
