Einstein never got a job in the USA ...anywhere, from Caltech to the other coast. This is why his backers actually made an institute for him (IAS). Oddly, his presence was perhaps the only reason why Feynman wanted to be at Princeton (besides his ego, oc).
Actually, he might have been much worse than that. I haven't read this yet, partly because it's 2,825 pages with 3,683 footnotes, but I'm guessing there's some truth buried in that length. It's a free download.
Oh - innuendo, and argument from...length of prose.
I looked up the "author" you cite - here are characteristic excerpts from his blog:
"Human beings have an enemy that has always sought to control the leadership of humanity to guide it into death. That enemy is the Jew...The Jews want to destroy creation. They will kill and destroy wherever and whenever they can. You are their target, and you lie still waiting for the bullet to reach you."
No, I'm not going to read any more of his or your bullshit, no matter how deep he or you pile it up.
So what? Just because someone says something you don't like, doesn't mean that they are wrong about something else.
"An ad hominem (Latin for "to the man" or "to the person"), short for argumentum ad hominem, is an attempt to negate the truth of a claim by pointing out a negative characteristic or belief of the person supporting it."
If the author valued logic they wouldn't go about blaming Jews for the world's troubles. It's not ad hominem to believe that an author's position is inherently illogical.
That might be true, for his position on jews. I don't know, as I haven't read much by him, just a comment here and there. However, his position on Einstein might be valid, and to ascertain that would require reading the book.
And yes, E. was a jerk to his family, at the very least: http://www.giagia.co.uk/2010/03/23/ada-lovelace-day-2010/
