A lot of people? I have yet to hear anyone accuse me of a being a troll. My point is your lack of understanding the difference between natural and artificial. If an organism is the product of genetic engineering, it's fairly obvious that the organism wasn't concieved by natural causes.

First, off, the statement, "X is unnatural" is an objective, not subjective, proposal. Describing a concept or affiliation as "unnatural" would imply it somehow goes against natural, physical laws, which cloning clearly doesn't for the reasons I just described. Human thoughts and affairs are fundamentally centered around physical laws, so any action we do is clearly not against nature. Second, opinions can be incorrect, or at least, very much so poorly-derived and unsubstantiated. So criticizing the opinion of another person on a subject is not some sort of argumentative taboo that people should feel the need to discourage. The only thing I argued against was the notion that there exist concepts that are, inherently, not "natural," which I feel I did a good job defending, and you've done a poor job critiquing. That is not an opinionated claim, it's a concept with a legitimate truth value that you can logically verify as incorrect.
