save to point out that the Levitical code is of minimal importance in most Christians' arguments against the current attitude to homosexuality: even the staunch supporters of Anglican Mainstream and other such groups have left that far behind them in the development their arguments.

That's very obviously untrue.  The issue of homosexuality is encountered a lot on Christian websites.  In almost every case the verses from Leviticus are used to attempt to support the common homophobic view.  You know that to be the case Andy, you don't fool anyone when you try to make out that it is not.
