There again we differ, "nut" to me has the connotation of mentally unbalanced or a lunatic or fanatic, whereas some religious people (my old great aunt for instance) are very sane people.
But that is just it, religious right are fanatics. You are talking of religious people, I was not talking of that, I was talking of religious right. While no doubt some religious people can be very nice (Mother Teresa, Jimmy Carter for instance), religious right are a bunch of fanatics.
