As you pointed out, it was the 70's for everyone, not just Arnold.
Even so, aren't you and others* on the Right giving him a free pass for his past drug use and orgies? Hasn't the Right in the past asked "What kind of message does this send to our kids? It's okay to take Steroids and use Pot and it'll be okay because in 20 years you'll be a big movie star and there'll be this democratic version of Bob Dole as California's Governor?"
* Like I said, I love the Right's hypocrisy. To paraphrase Sean Hannity: There ought to be a statute of limitation for stuff that Politicans have done in their past.
I guess that only applies to Politicans on the Right. It's about Character, honest.
PS: I could point out how sad it is that those heathens on the Left are the ones who are having to point out the immorality and character flaws of Politicans. Says a lot about the moral rightousness of the Right.
