- I don't like X. I don't like bad things. Therefore, because I don't like X, X is bad.
That is an example of a faulty syllogism.
However, "bad" is a value judgement. Apart from some means to objectively make such judgments, what is "bad" is what you don't like.
(I am not 100% sure that there is no such thing as objective, or semi-objective, valuation, however. If one assumes commonalities between human beings, at least at some basic level, one can postulate some form of common valuation.)
- Any examples which run counter to my point are due to observer error, not any mistakes in whatever my point is.
This is only poor logic on the basis of the word "Any". It is quite frequently true that people will offer anecdotes to counter a point, but that does not mean that the anecdote is a valid counter. The rational person must consider the possibility that the other speaker is (1) mistaken in his observation, (2) mistaken in his characterization of his observation, and (3) is lying because he wants to firm up his position (to make it ironclad, as it were).
When someone solicits the opinions of others, and then reports on those opinions, you also have to consider how well you believe that person can sift the aforementioned factors.
For example, let us say that I claim to like eating strawberries. You need to take the context into account, as well as your general estimation of my personality. If you are offering me strawberries, and you know that I am the kind of person who is likely to avoid giving offense, you are not at all sure that my claim is true. Indeed, your subsequent observations may lead you to believe that my claim is false (I only eat one or two, and do not seem to enjoy them). Even if I do seem to enjoy them, you do not know that my claim is true, because you have reasonable grounds to doubt my motives about that claim.
On the InterWeb, where everyone wears a "mask" of sorts, and one cannot directly observe the "speaker", this problem is compounded.
The rational reader has to ask himself at least these questions:
What do I know of the poster? Has he been generally insightful in the past? Has he been generally truthful in the past? Does he admit errors, or does he take offense when error is suspected/pointed out? IOW, how much of his self-worth, in my estimation, is tied up in his being correct? The less likely he is to admit error, the less likely his anecdotes are to be trusted.
How rational does the poster appear to be? Should I assume that he is interpretting data correctly? Is the data he is relying upon hearsay? (And hearsay includes "My players say.......")
Not to put too fine a point on it, do I believe that, confronted with the same direct evidence that the poster is supplying indirect testimony of, that I would draw the same conclusion as the poster?
Does his anecdote make sense, within my experience and to the best of my knowledge? It would be a poor reader indeed who decided that Gygax was a major fan of 4e in the afterlife simply because I claimed his ghost appeared to me, told me so, and aged me 10 years.
Any disagreement with my point is because my point is being misunderstood. I will further refuse to actually clarify my point because, that will also be misunderstood.
This is only irrational on the basis of the word "All".
You have claimed being misunderstood many times yourself, and you have misunderstood others many times yourself. As have I. As have we (nearly) all.
Intentionally or not, misunderstanding the other poster seems to be a normative for InterWeb conversations.
