<<hummn... rhetorical, is that what you call your 'strawman?'>>
Nope, two entirely different concepts. Rhetoric is artfully arranged or contrived speech, configured for a striking or memorable effect, for maximum effectiveness in delivering a particular message, for creating or defusing a mood or for some purpose related in some way to the creation of a desired perception in the mind of the listener.
A strawman is a target or issue set up to draw attention or fire from an issue which the person setting up the strawman wants to avoid. A strawman can be set up without any rhetoric at all, although of course it would probably be more effective as a strawman if some measure of rhetoric were to accompany its creation.
