Failing to meet moral standards means you had those standards to begin with, whereas the hypocrite probably never had them at all.
A hypocrite is a person who doesn't "walk the talk". In general liberals don't talk traditional morality....hence they can't be hypocrites with regards to morality.
Conservatives do "talk" morality hence they can be hypocrites.
That's why when Republican Congressman Mark Foley was outed as a pervert he resigned in disgrace. While the Democrat pervert Gary Studds, when outed, was given a standing ovation.
And I might add they despise traditional morality and those who say we should abide by it.
