It's not a matter of the veracity of the bible.....it is the matter of choosing specific parts of the Bible, to preach out loud, to reinforce an agenda.
Mike Overd wasn't prevented from evangelising, despite there being long-standing concerns over him doing so, from the Police, etc. He has, on numerous occasions, used the same message; he was prosecuted in 2012 and the case went in his favour.
You and I both agree that the Bible and many of it's teaching are dangerous pernicious nonsense and I, for one, would like to see an end to *all* street-preachers, or whichever kidney. I can see no reason why the Bible should be held in any esteem...and the Court system now allows people to 'affirm' according to their own conscience.
