whats moral relatism (phylosophy)?

Answer 1

I think you mean "moral relativism (philosophy)"

Moral relativism is the idea that morality is relative and can change with society.

Everyone will believe that SOME morality is relative. For example, it might be considered immoral to drive down the left side of a two way street in the US, while the opposite would be true in England. Wearing shorts might have been viewed as immoral in 1650 Salem, but is common in 2006. Other types of morality are seen as relative due to cultural differences. Marrying a first cousin is considered a taboo in the US -- while it is accepted in certain cultures.

All of this contrasts with those who view morality as absolute. Every culture views murder as being an immoral act and most people would agree that this is not constitute a relative value (though they will argue over what constitutes murder).

Where things become interesting is when some people in a society believe that a certain act is a relative moral problem while others do not. Abortion, homosexuality and living together without being married fall into this category. There are those in the US who believe that these acts are immoral and will not accept the idea that they can be thought of as anything else -- and there are those who do not believe that they are immoral acts.
