Once again the perception of religion on JUB is so skewed as to be oblique to reality. Icelanders are overwhelmingly Lutheran in profession, but little of anything institutional in practice (very few are attenders) and are therefore termed nominal.
The idea that only conservative movements oppose pornography is an imputation that is not nor has not been accurate, either in Iceland or elsewhere. Most social progressives, like feminists, absolutely oppose pornography and the objectifying of women (the vast, vast majority of porn is heterosexual of course, along with the demographics.) Then there is the tendency of it to drift into pederast pandering, as it so often does on JUB with the posting of pictures of underage subjects or certainly the appearance of subjects who intentionally appear underage.
That other causes are more important probably gives the impression that the Left is supportive of porn. Whereas many on the Left would not want or bother to attempt censoring porn, to portray them as pro-pornography is a distortion and just wishful thinking.
Social conservatives and religious conservatives may embody many undesirable values where gays are concerned, but they are not some enclave of opposition to pornography: a lot of the Left shares the view that it is not a positive influence in society, and for many, it has nothing to do with religion.
