I was referring to the idea of them calling themselves "enlightened" as being pretentious.
I'm not sure about "pretentious", but certainly "presumptuous". Not believing in God does not mean not believing in other kinds of woo.
Aren't they referring to the Enlightenment?
yes they are, but your average person in the street doesn't know that. Also, even knowing that, if I call myself enlightened, I'm bracketing myself with such greats as Voltaire, Hutton and Locke. That seems quite presumptuous to me. I am not their intellectual equal
I think the notion of terms that are recognisable and have relevance to the man in the street is quite important.
So I guess most people may have an understanding of an atheist. I doubt more than a handful would understand 'bright' or 'enlightened' as terms. Nor would they understand 'strong atheist' or 'weak atheist' - in part because there is no relevance to their lives. People aren't badgered by atheists on a day to day basis - the news isn't full of atheists creating problems around the world due to their atheism - so categorising atheists into strong and weak just does resonate.
Now the same cannot be said for the extra descriptive terms used for religious people, e.g. extremist, fundamentalist, evangelical. These are very real and very relevant because we see the (often negative) consequences of extreme, fundamental, evangelical religion daily when we turn on the news.
