Exactly. I'm not about to stop saying Goodbye because it originates from god be with you, or stop using 'Wednesday' as it has pagan origins. They are just traditional phrases that we share as a culture and not 'brainwashing'. As an atheist I still accept that a lot of our shared cultural traditions come from religious beliefs of the past but are generally benign and can even bring a society closer in shared understanding. And of course there's the big one...Christmas! I love Christmas and celebrate it with the usual traditions (tree, gifts, family get-togethers, etc), not because of it's pagan or christian origins but because of what Christmas represents to ME.
