What I find disagreeable is the argument, put forward by some Christians in the media, that someone who is now an atheist, but was brought up as a Christian, is still governed by "core Christian values". The 'core values' are not peculiarly Christian, any more than they are Muslim, Hindu, or atheist, but are universal.
Faith does not need a seat at the table in public life. Honesty and the other universal values do.
The idea that we need to be confident in our own religion in order to fight religious or other oppression, if I read the Baroness correctly, is ludicrous. Atheists will fight it just as keenly.
