assuming all I read was:
"I believe in Spinoza's god"
That would be enough for me - Einstein was famously economical with his words. Those 5 words tell me he was a pantheist.
In any event, I am not interested enough in Einsteins religious beliefs to read a book devoted to the subject - my next related book will definitely be about Spinoza.
I love how you speculate on what 'athiests' will or will not do and their reasons for so not/doing Kate - you need to brush up on your critical thinking skills hun.
