So... Because of the fact I can exercise Rights that others are denied, I am somehow obligated to sacrifice my Rights until everyone else can exercise them. Now as for those who are denied the ability to exercise their rights... what sacrifices do you believe they are obligated to make in order to gain the ability to exercise their Rights?
Sacrifice means giving up something you value for something of lesser, or no, value.
You have said that we, as Americans, have an inherent obligation to sacrifice our own Rights and Freedom for anyone who is denied the ability to exercise those same Rights and Freedoms. It's like claiming that my Right to Free Speech obligates me to wear a gag, and remain silent, until every single person on planet earth has the same Right.
The quote clearly states that all men are created... with certain unalienable Rights. So claiming I have an obligation to provide others with something they already have, something every single one of us is said to have been created with, simply defies logic. If you think you have some "right" to deny me the free exercise of my own Rights (until such time as everyone on planet earth can exercise the same Rights I'm now being denied), then you are no better than the thugs and dictators you claim to oppose.
According to who???
My only obligation to my fellow man is to NOT violate his Rights in the process of exercising my own.
