Reply #104: Maybe it's along the lines of one of these:

[No Elephants]

Building one or more straw men;

Using analogies that aren't really analogous;

Moving the goalpost after a poster has fully answered, or even refuted, your prior post;

Changing the subject after a poster has fully answered, or even refuted, your prior post;

Putting words in another's poster's post or pretending you're proving or teaching something that is already in the other poster's post and, by the same token...

Ignoring things in a post for which you have no answer at all.

Just a wild guess.
