Einstein never said or wrote those words.
All mental states are personal in nature. Generations, nation states, all cohorts of individuals have disparate qualities, beliefs and behavior.

There's a lot in what you say; however many mental states have physiological causes, so we can't really allow Muslims to stone to death schizophrenics for example, and not interfere with their barbarous behaviour for fear of infringing their human rights to practice Sharia law.
