> I KNOW, but it's a harmless rhetorical device. I don't really care but but when I found out the actual meaning of the phrase (the usage of which never really made sense to me), it made a lot more sense to me. I thought it was interesting. I'd also argue that "it's harmless" is not always accurate. It's usage dismisses counter-evidence to a statement. Depending on the case, it may or may not be harmless.
