I am looking at finding the name for the rhetoric style which uses two contradictory statements, one positive and the other negative, with the first seemingly giving a sense of positiveness or neutrality to the other.
For instance:
"You are an intelligent person, but everything you think, say or do is stupid."
In the above sentence, the two parts are contradicting one another, but somehow the first part being flattering makes the second seem less insulting.
What would be the name for this?
