Well, in Britain 'social conservatism' refers mainly to traditionalists, as opposed to neo-cons or economic liberalists. Such people would not vote Conservative because of their love of money and big business, which we think is harming the culture of the country. And we would not support the neo-cons as we don't regard them as being particularly conservative in many of their beliefs (i.e environment, foreign policy). Needless to say, the likes of the BNP are not socially conservative, they are far-right radicals.
But we are also against such things as rampant political correctness and the hedonistic binge-drinking casual sex culture that has enveloped modern Britain. There aren't really many of us, and we have nobody to vote for Hope this helps.
