Whether religion needs this sort of protection is an interesting question. But the NSS contributes nothing to this debate by putting out a press statement that can be accurately summarised as follows: "it's not FAAAIIIRRRRRR......" In fact this would accurately summarise most of their communiqués. When I first became aware of the NSS and similar organisations, I found them quite threatening, imagining them to be a real danger to the freedom of faith and conscience that we enjoy in this country. But the more I hear of them, the less I can take them seriously.
There's a real problem with an organisation that exists with a purely negative purpose. It has nothing positive to aim for, no achievements to celebrate, nothing really to contribute to the greater good. The cause is not really one to stir the passions or change hearts and minds. In the case of the NSS, this is made even more painfully obvious by its own mission, "challenging religious privilege", setting itself up to knock down something that probably doesn't exist anyway (how ironic). Religious privilege? In which country are we talking about? Probably by "privilege", they mean the fact that religions are allowed to exist, which explains why it is so easy to get up their nose simply by mentioning any faith-related issue.
These negative press tactics are not the preserve of the NSS, of course. Christian organisations send out their fair share of sulky press releases. But these are just unfortunate excrescences on the edge of the Christian witness. Strip them away, and underneath is a message of life-changing love and hope, a matter of life, death, and destiny. With the NSS, there is nothing else underneath. It's just a bunch of people being grumpy about the fact that not everybody plays the way they want them to. There's no future in that.
