Note incidentally that while you might be able to use the word that way, the vast majority of people who use it seem to use it in a way closer to what sketerpot is talking about. If one interacts at all with either young earth creationists or homeopaths for example it often doesn't take long before the term is thrown around.

In my experience scientists arguing with creationists (I haven't looked at arguments with homeopaths) frequently make the mistakes I list above, as well as a few related ones. In particular using the AJ Milne quote ciphergoth cited in an argument against creationism is itself at best a straw man, after all the creationist also cares about getting the facts right, in fact that's why he's arguing with the scientist, because he believes the scientist has his facts wrong.

In any case the underlying argument in the AJ Milne quote is: all people are about truth; therefore, you should believe what science has to say about subject X.

This is an example of either (1) or (2) depending on how the implicit premises are made precise.
