Morals, values and beliefs are terms that refer to the ways people think, behave and react. These three terms are often interchanged as having the same meanings. However, each has a separate meaning of its own. Each term builds upon the other terms, beginning with beliefs. Values are a type of belief, and morals are a type of value. All three terms refer to ethics, which deals with a person's conduct.
All are subjective, what was once the norm is not prohibited, what was once abhorrent is acceptable, what is now acceptable in one location is unacceptable in another.

In our current culture there is no outrage over a well turned ankle as there was a hundred years ago, and in Europe going topless to sunbathe is the norm. In Japan the back of the neck was more an erogenous zone than was the breast.
To say that something is 'intrinsically and morally wrong' can't be done in a world that constantly evolves and changes its morality.
