That story about Fonda and the note is a lie. Not that I would put such an act past her, but this never happened. And, IMO, whoever started that story is just looking to discredit those of us who are opposed to America haters like her.
There is certainly a lot of truth to that story. The note thing may not have happened, but she very much professed her disdain for the American soldiers (POWs) and made no bones about it - to their faces as she was a great pal to the Commies.
I’ll never forget her engagement out here in Texas about 8 years ago. I was one of the protesters and greeted her limo with my sign “Jane, you ignorant slut!”
The local news were covering the story and the producer saw my sign and told the camera people to be sure and NOT get me on film. :-}
