Where Einstein made a statement about physics one can legitimately cite him using an Argument From Authority (though Einstein might still be wrong his remarks would carry weight because of his stature in that field).

Where Einstein made remarks about things other than physics we ought to examine his supporting arguments as closely as we would examine anyone elses. Since this is the internet no-one's credentials can be examined so everyone's argument is worth as much as they are prepared to back it up with facts, checkable references, and manifest knowledge of what they are talking about.
