My problem with things being "good" or "bad" is that it's divorced of context. Carbs are not good or bad, but they are certainly bad in certain contexts and good in certain contexts. Different diets can be effective for different things. Some people are actually trying to gain weight, some people only need to change body composition, some people tolerate high fat well, some people don't etc.

So I agree with you, and my point is not to say that carbs are good for you or bad for you, but that anyone saying a major macronutrient group is good or bad without context has a large burden of proof.
