Hardly. It implies an equivalency between the MOTIVES, but not the values.
as if because they believe something they are in some way enobled.
Not "ennobled." Rigid. Unbending. Ideological. The same way many right-wing idealogues tend to be.
I reject this out of hand.
As is your right. But that in no way diminishes the validity of the argument.
The Left was, is and will always be motivated by ...
Raimondo tends to be libertarian to the extreme, but not necessarily left-wing. In any case, your ascribing certain motives does not make much of an argument. Whatever their motives, the Left has intransigent, principled (albeit deluded) people in its ranks. That they have chosen to invest their energies in such a reprehensible ideal does not diminish either their enthusiasm or their integrity. It DOES call into question their sanity, but not their commitment.
Insanity? Raimondo considers himself to be the only sane one. Yet he advocates a position that would end with our destruction. The operation was a success, but the patient died.The Left and radical Libertarians have no moral standing, having jettisoned the very concept of morality descending from a sovereign, holy God without whom "morality" becomes a political football in the hands of the ruthless. Raimondo is no different, leaving him with no morality per se, only self-righteousness.
