straw man is suggesting arguments that have not been made in order to ridicule them.....

Suggesting that "...ALL remarks about conservatives are "Clever things with double-entendré remarks" is such a usage, even when asked in a rhetorical way. The example feels like 'bait' to change the issue under discussion.

" I DID NOT state that YOU were talking about conservatives." ..of course not....but the choice of examples seems to imply that I should.

As to 'sometimes objectionable treatment of minority viewpoints'...it happens to all viewpoints at times, although I still do not see the volume here that would make THAT a good choice of examples. One's choice of examples, just as in one's choice of insults, steers the conversation awry.

   It is, sadly, the case that many extreme conservative viewpoints are expressed with a rigidity and attitude (ala Rush Limbaugh and Ann Coulter) that make it VERY hard to debate certain points seriously. (No...I do NOT think that 'most' liberal viewpoints employ similar rhetorical devices...so pointing out one example won't convert me.)

short version of all this: It felt like bait.
