Sorry, I guess I was braindead too. What I meant was, if you have to choose something, as in a particular something, not a general something. Like "If you have to choose a, that's not freedom". If you have to choose good, that's not freedom. That's what I meant.
by culture, there's also a time factor. People of a thousand years ago had different morals than we do now. You're only looking at the really obvious things like murder, but morals go much beyond this, and there are many, many gray areas. Like Homosexuality, for example. Abortion. Etc.
I was just trying to say that I don't think true freedom is doing whatever you want, because in the end, you are not really free. In many situations, people are forced to do the wrong thing, even though they don't want to, and then they suffer the consequences of their actions. For example, being forced to kill someone or steal something.
I don't know if those are gray areas. More like issues that people have strong differing views on, which create ugly, ugly debates-- especially on the Internet.

But just because there are different views on it does not mean we should say they are all valid for the sake of respecting people's opinions.
If something is morally right, or wrong, I don't think it changes just because a culture starts to accept/ reject it. Like I said, in the past, slavery was acceptable. Was it morally right then to treat other human beings as objects/ possessions?
If I came from a cannibalistic culture and wanted to practise it here in Canada, a multicultural society, could I? If you refuse, could I say that you are being racist and inconsiderate of my culture and personal morals? Is terrorism ok if people were just brought up in that kind of culture? Maybe we can say it's not their fault ( children brought up to hate, conditioned by their parents/society... the westboro baptist church comes to mind

), but you can't say that the terrorism/hate crimes themselves are right.
I'm not saying one culture is better than another. I see lots of issues with my own culture, as well as my own personal views on certain things.
