How is one culture supposed to judge another culture? Everything is relative...
Until you actually get told otherwise by your conscience.
Well, from my philosophy courses in college (as financially useless as they may have been) there's actually been a lot of study and attempts to codify what should be regarded as Universal rights. There's no need for us to rely on our "conscious" or someone else's conscious nor should we sit back if we feel that human rights are being abused in another nation that is sovereign. I'm a very liberal open minded person. If you want to worship some stupid magic person in the sky, go to town. If they start to infringe upon others' life, liberty and pursuit of happiness, then we have issues that must be remedied.
Your lax definition of a 'Conscious' be damned, begin the escalation of political pressure then economic pressure then physical pressure.
Sort of on topic, from your signature:
Except for ending slavery, the Nazis, communism, & securing American independence, war has never solved anything.
The Nazis were stopped because they blatantly violated (nearly) everyone's rules of Universal Human Rights -- so much so that many of their own detested it. And we should not allow something like the Holocaust to happen again. Communism, on the other hand, is a counter case. We went into Vietnam under the laughable pretenses that a Universal Human Right is capitalism in place of communism (with obvious self interests). Believe it or not, communism does not blatantly violate everyone's rules of Universal Human Rights and so we were kind of lacking on the support and moral high ground for that war. If you think communism has been "ended" and that it has been "ended" by war and not inherent corruption that it can't seem to shake -- you and I must be reading different books by very different authors.
To recap, Universal Human Rights transcend your suggestion of relativity. I'm not sure but if you're attempting to make fun of people who tolerate other cultures by saying it's relative, there's no place for that when you're dealing with a child's life and their attempt to be educated.
