The new tactic by those on the left of the political spectrum is to cite every argument that they cannot win as ‘a republican talking point’. They do this in order to suggest that the entire subject (or at least your point on a topic) is tainted and that you, by using it, are unworthy to offer an opinion. Further, they suggest that they will not respond because to do so furthers the republicans agenda. It’s like a verbal ‘get out of jail’ card.
