If a hypothetical is unspecified, and you ask for it to be clarified, then that isn't fighting the hypothetical.

Unfortunately, people will rarely actually do that. In particular, I've yet to see anyone else ask, much less answer, what appears to be highly relevant information in the classic train-switch dilemma: what are these people doing on the track?

2) People are often too ready to consider things as a trap. Some people will claim that any convincing or hard to argue against statement is a "trap"

The problem with hypotheticals is that they're fictional evidence that you're asking people to generalize from.
