Indeed it is. And it is no secret that religion has been used as an excuse/justification for the laws put into place even recently in one or more of the states in the US. Not gonna get into it coz it might get political but anyone who doubts it can just google it for themselves.I don't know where you live, BUT "Now and Then" is set in contemporary USA, you know.
Point is: some laws dont make sense and in 'Now and Then' that one law might be from one such state government even if it is not so on the federal level or whatever people call it over there.
