" 'Atheists but culturally Christian here too'
That's like being a vegetarian that eats steak. confused"
Nope. It is possible to believe in many of the philosophies of Christianity, to have grown up with the parables and have absorbed them in to your thinking, to have deep familiarity with the major church festivals, to know the Lord's Prayer, and not to believe on God or any god.
We live, culturally, in a Christian country. Whether we believe in God or not our constitution is built on the relationship between church and monarchy. Our laws, culturally, reflect Christian roots: Sunday trading laws, bank hol on religious festivals, laws around marriage and so on. Manu customs also reflect Christian roots.
These all form the way of life that is culture.
If Christianity has the privilege of a place in our establishment, Bishops-go-Free in the House of Lords etc, Christians don't get to say non-religious people cannot claim to have a cultural link to Christianity.
Such arrogance!
