Reasonable answer. I have a bit of a different one, being pagan, as [MENTION=4939]kyuuei[/MENTION] pointed out.
I agree stereotyping can be an issue, and I certainly don't like it from a pagan standpoint; but there are certain common attitudes in a religion despite the great variety. Since there are so many branches of Christianity, with each person lending their own personal spin on things, of course there are radically conservative as well as radically liberal people and everything in between, each citing their own Biblical references. But there are some things, particularly those which differ from paganism, which are pretty specific to the religion and difficult to moderate.
Pagans refer to the general public as "mundane;" there are huge differences between the average person and the average pagan. Perhaps attitudes about sexuality are becoming less traditionally Christian and more pagan, but paganism still is not close to being widely assimilated into people's minds. Paganism views sex as a fusion between the spiritual and the physical; this view is shared with Christianity. We just have different views on the nature of the relationship and how it works. So doing it right from a pagan standpoint would involve much more than just physical sex. It doesn't require romantic love, or a legal marriage, or devotion to a particular deity, but it does require mindfulness of the interconnection of all things and the process of creation, as well as a spiritual agape sort of love for the partner/s. This connection is what you correctly say is lacking from the attitude of popular culture. Popular culture still doesn't know how to fuse the spiritual with the physical, so they tend to do all one or the other.
So what you are saying about mainstream practices is largely accurate, but it is not due to paganism, nor does it apply to pagans. I find my lifestyle to be the most liberating, fulfilling, and loving one I've come across.
Yeah, that would be me.
Sorry.
No, I don't really hate Christians; I just like to criticize their belief systems to see if they are logically consistent. Of course people have a right to believe what they want regardless of logical or scientific validity, but when they become proscriptive to non-Christians I feel the urge to have a dialogue.
