i really don't know how i feel about this assertion that in order to be able to criticise religion you should be a scholar in it. i joined the national secular society recently because i believe religions should not be above criticism (they'd certainly like to make that illegal, and that goes for the CoE as well as all the others) and i want them out of government, education and for it to be a private pastime.
theres certainly a lot of evidence that islam like any religion has perpetuated divisions, violence, misogny etc. i think the same of the catholic church etc. i'm not saying there is no value, or that everyone who follows those faiths does those things - but on balance i believe the negatives far, far outweigh the positives. and i'll damned if i need to suddenly become an islamic scholar in order to level criticism at it, or its interpretations, or some of its adherents. theres too much at stake to remain silent, sorry.
I'm not sure how this relates to my bit you quoted, but fwiw I have a lot of sympathy with the NSS - the affiliated "New Humanist" magazine is well worth reading and I've known a few people who were NSS members or worked there who were sound.
I think my main objection to all of this is the way that all other aspect of life except religion manage to get filtered out. Bad things happen purely because of religion and not because of other factors such as culture, politics, economics etc.
For example it is clearly pretty lazy to suggest that the conflict in Northern Ireland / the six counties is a religious one.
Similarly the intense scrutiny around dancehall and homophobia has usually given the bible as the root of the cause which kind of ignores the most critical aspects of how come all these people ended up in Jamaica and reading the bible in the first place.
Whilst religion clearly hasn't helped these situations it is naive to suggest that it is religion and religion only that we should be criticising.
The rabid ranting about the evils of Islam that there is so much of these days is overly simplistic and unhelpful. It ignores the other factors completely and turns the situaiton into a battle between christianity (or "christian values/civilisation) and islam. This only serves to reinforce the idea that Islam is one thing and it is Evil. This doesn't leave much room for people who happen to be Muslim but who aren't nutcases. The whole tone only serves to whip up anti-Islamic sentiments, which creates more of a divide, which intensifies the feelings on both sides.
