Your premise is, er, well, um, how can I say this, wrong. Conservatives dont eat their own, but arent going to bend over backwards to help someone who has plainly damaged themselves. Bennett's case is really a non-case, what he did was legal and he never tried to hide it. What if he had spent millions on Hostess Ding-Dongs? Gluttony is about as serious as casual gambling.
That having been said, conservatives do tend to lack vigor in defense of their fellows, and that can be a problem. Something about the rugged individualist nature of conservatism, the value of being responsible for ones own actions, that prevents other conservatives from jumping into the fray uninvited...JFK
You are entitled to your opinion; yet, I think it is a problem. Conservatives are too quick to judge other conservatives, they are slow to defend and quick to ostracize.
You don't call that a problem?
