Holocaust scholars? I'm sure they did cause they're always unfailingly correct. Yet they didn't boo it off of the Holocaust stage did they? They used it to reinforce the Holocaust lies.
'Tis a good point. It's true that some mainstream holoscholars questioned the veracity of the story. But the ratio of how incredibly ridiculous the Mischa story is to the popularity and legs of the Mischa story is mindboggling. And it's not as if the holocaust industry had no experience with fraud prior to Mischa.
It just goes to show you that there aren't any holocaust survivors testimony too stupid to be believed, at least at first. Just make sure you don't pull a Rosenblat and give your fake holocaust memoir a happy ending. You can say whatever you want about the holocaust as long as what you say sounds bad.
