Actually not. Quotes are also put around peculiar usages and ironies.
However, go to Cain’s interview about abortion a few weeks back.
See the Hill’s: “Cain: Abortion should be illegal, but families will decide whether to break the law in ‘heat of the moment’”
It’s patently dishonest to put a quote like that in your post, implying Cain said it, when he said nothing of the kind. Is that your idea of following the Golden Rule: smearing a person w words attributed to them that they never said?
As to the interview, you’ve been taking Cain’s words out of context ever since he said them. Dozens of FReepers have pointed this out to you. It’s flat out dishonest. You should be ashamed.
