Another time I get really annoyed by logical fallacies is if the logical fallacies are commonplace.
I do really hate it when something that doesn't make sense is extremely commonplace. For instance, when people treat the statement "a positive attitude creates a positive situation" as an ironclad maxim, when it isn't.
It's something that is true for some situations, but not for others. And the thing that bugs me is that it's something that would be obvious if they just thought about it for minute. If that rule were true, it would effectively mean that victims of crimes must bring it on themselves.
If a person is robbed, they find themselves in a negative situation. Therefore, if it were possible to bring about a positive situation just by having the right attitude, this means that the found themselves in a negative situation as a result of their attitude. This is because, if they had a positive attitude, they would have found themselves in a positive situation, not a negative one. The mental states of the victim seem to play more of a role in the crime than the criminal!
There are many other cases where the "attitude" one has cannot possibly have an effect on the situation.
There are other examples of illogical thinking that are commonplace, because people repeat them either because they haven't thought about them, or they care more about how it makes them feel than how much sense it makes. That was merely the one that came to mind.
