Values is a term that means the set of beliefs that a person has. These can be based in religion, or not. A country generally has a set of values: ideas that are generally considered good and morally sound. For example, a Chinese value is profound respect for one's elders, correct? A Christian value is that sex is prohibited (not allowed) between non-married people.
OK, so assuming that you now understand the concept of values,
When a person makes a value-laden statement, he is implying that whatever he is saying is fact, rather than an opinion. Values are not inherently true. Take the Christian value, for example. Although pre-marital, non-monogamous sex has its risks, it is not inherently bad just because the Church says it is. However, a person making a value-laden statement is assuming that you agree with him, and if you don't, you should (again, because what he is saying is "a fact.")
This doesn't mean that the values of a particular person or culture are bad, just that they are based in emotion and subjectivity, not impartial data.
You are not stupid! Out of curiosity, I looked up value-laden in the dictionary, to see what you might have seen, and it is no wonder you were confused!
I hope my explanation is a little more clear, but please ask for clarification if you need it. :-)
