Isn’t that the same thing of being governed and what your government itself allows you to do or not do? Or whatever alternative government you may be at within.
Though I do agree to the morality issue to some whom been relating to on human rights. In truth you have the right to do anything when you think about it, although any actions may be held against you depending upon what they may be and what laws you are governed by; or the laws in which you have to follow if you are in another region instead of your own. After all, different countries have different ethnics and some countries aren’t even blessed in rights for their people.
Not everyone is ruled fairly and justly and equally.
So, lets see here.
The answer to what constitutes a human right than anything else may be here, in wikipedia: http://en.wikipedia.org/wiki/Human_rights
That is a general idea which I agree upon in their description, also you can find info about them in various nations.
Depending on where you are, once more, the protection to a human right may last as long as the government or a move of the people states it does. Times change, so do laws and ethics.
Should it be restricted? Depends, normally the answer to this will be no, though depending on what right it is depicts if I agree upon the purpose of its restriction or not. There are plenty of deemed human rights out there that I don’t fully applaud.
Can it even be restricted? Why, absolutely! Your government rules you and they can take things away, though depending on how you are ruled and whom rules you(as in what nation) there are procedures to this. United States is more flexible and as we know, things have to go through various offices before a change can be made, though I am unsure if amendments have ever been taken away. I’m sure they(amendments) may have been corrected or went through changes over time, but I’m not entirely positive if any has been done fully away with. As far as other nations go, especially those more with a dictatorship, they can do whatever they want and you won’t have much of a say.
