I can't make out the actual substance of your critique of Schwarzenegger here. I'm just pointing out that the claim that he's "the most undignified and embarrassing German speaking export in history" is obviously ridiculously hyperbolic regardless of your disagreements or differences with him.Tbh , from what I`ve read I assumed you to be sophisticated enough as a poster to know how to estimate my comment.
Anyway, the most remarkable thing to me about his speech is that Schwarzenegger still seems to confuse reality with the easy-structured, martial and sentimental world of the movies he was acting in. Being a decent guy does not mean that you can`t be an ignorant. In combination it can make it even a lot worse in the end.
Leading further to the probably more relevant question what it tells about Hollywood and the mental state of the country that such a limited and simple-minded personality, similar to Reagan, was in the situation to become a famous actor and even politician. Btw. independent on the different background this could be similarly argued with Trump and most of the other previous presidents.
The actual danger to me is how seemingly careless/blind US society as a whole seems to deal with the actual crisis accompanied by a miserable staging in the medias. It looks like the whole country is running with open eyes into the abyss while once again very likely people in other parts of the world will have to pay the main price for that.
