"I don't care about..."
Sweeping facts off the table is a common technique around here. Those facts are highly relevant to this discussion.
It is perfectly true that Clinton's behavior in office (to make an example) would be irrelevant if some other politician were trying to justify their own immoral behavior in office.
But if Clinton were, hypothetically, making speeches to the media and others accusing that politician of immorality, and declaring that that politician should leave public life because of it, that would be a bit different, wouldn't it?
House members now screaming about Hastert cutting slack for Foley tolerated deviants in their own ranks for years. That's politics, not morality.
