Thanks for some very balanced viewpoints, Brett. As you quite rightly, and with a much welcome and refreshing objectivity, point out the interpretation of the holy scriptures in any religion can be many and differing. There will always be a small, fractious minority in any group. They've always been there and they will always be. As long as we have religion we'll have these problems.
Like you, I also believe that any threat comes from radicalised groups already within the country but here I'm talking not only about Islamist radicals but even right wing radicals who actively keep the pot boiling with resultant scaldings all round. They are just as dangerous and I believe, just as many.
My views on the media I've already mentioned so I wont, go into them again but it's refreshing to see that there are others among us who also read critically.
