Joybringer,
I'm not a huge fan of Solzhenitsyn, I don't think he is that hot a writer, BUT you are being unbelievably harsh. Solzhenitsyn wasn't loyal to the then-current government in his country, which he considered, wrong, harsh and oppressive. He had plenty of cause not to be keen on it, after all, his parent's way of life was destroyed violently when he was an infant, his family's hard-earned property was confiscated and he had to practice his faith in secret, as well as never being able to talk about who his father really was. Then there was the long period of imprisonment and abuse.
Solzhenitsyn was imprisoned under one of the treason laws, but when you consider that what he did was write a few uncomplimentary comments about Stalin in a letter to a friend, then I would suspect that you are just as guilty of such 'disloyalties' and 'unpatriotic' actions as he was.
I don't see anything unpatriotic in Solzhenitsyn, even though I disagree strongly with most of his politics.
