That’s really unfair. Being German or being fluent in German doesn’t make one a nazi.
Nothing against Germans. But what did she see in this man? Did they share ideology? I mean, if the guy has been sig-heiling and has Hitler painted on a surf board mounted in his office, she had to know about it. Her German ancestry and cultural ties, absent the marriage to a neo-nazi, would be nothing. But, in this case, they are cause to suspect if you ask me.
