Well, not really. When the US was founded, all adult white males who were landowners were considered equal. White males who didn't own land, nonwhites, and women were SOL (sadly outta luck). I'd say a true, fair, decent set of moral values is a prerequisite of democracy. A true, fair, decent religion can provide these moral values, but these moral values do not necessarily have to be provided by a religion. No, freedom of religion just means you have the right to choose which faith system, if any, you would like to follow. Beyond acknowledging that religion as defined by humanity exists, freedom of religion isn't really a religious concept.
