And I'm right, because after all, thats my opinion, and opinions can't be wrong
Of course, opinions really can't be wrong. They can only be unhelpful. Your example actually demonstrates the real problem that often goes unnoticed: too many people don't understand the difference between fact and opinion. The second clause is after all a factual statement, though a false one. When understood that way, we see that the only part that is opinion is "All people should starve". You could say it's "wrong" because it's based an incorrect statement, but that's not a meaningful assertion. By definition, an opinion can't be evaluated in terms of true or false because it isn't making a factual claim, but only in a subjective manner as right/wrong, just/unjust, good/bad, etc.
Let me put it this way: An opinion doesn't tell you anything about the topic. The only information it conveys is one's feelings about the topic. As such it is an expression, not a claim, and contains no useful information.
