Buzz Click has fallen a couple of notches because of this indefensible position. There is nothing right about a 40-something year old who has sex with a child. Yes, terrible things happened to his family more than once, but that doesn't entitle him to a "Get out of a child rape charge free" card.
Frankly, I think the reason for the insane defense is entirely tied to politics.
One thing that the left does well is fabricate a tale and stick to it at all costs. And this story flies in the face of one of their more successful yarns - that " those on the right are perverts and child rapists, even though they claim to be 'Family Values' people". -- So, everyone on the right ends up tied to a sex crime or some sort of perversion (Foley, Catholic priests, Craig, Sanford etc.. ) And in some cases, some on the right are persecuted for such things even if they never happened at all (Beck, Limbaugh, Coulter etc.)
However, when someone on the left is caught with their pants down, it gets minimized or dismissed altogether-- Even when real people are actually hurt by these sociopaths.
The Kennedy boys were all philanderers -- no big deal..
Barney Frank and the basement gay brothel ? - meh..
Elliot Spitzer and hookers - So What ?
Gerry Studds Bangs underage boys ? - Let's Reelect him !
And so it goes...
