Frankly, I don't think what Arnold said, or to a lesser extent did, in the 70s matters much. Of course, that's a "republican only" standard, for whom youthful indiscretions happen well into middle age, but still.
As for his Nazi fondness, his closeness with Kurt Waldheim was far more disturbing. And, his belief that women's breasts are public property is still more disturbing. I'm pretty disgusted by the general "boys will be boys" tolerance of this bullshit. It's a crime. Misdemeanor sexual battery at a minimum.
But, anyway, here it is. This is really old news/gossip, but it's hitting the mainstream.
