I'm sorry but they shouldn't entertain christening a bastard. If something's worth doing then do it properly. At least the child has a step mum they'll never meet.
Thank you for reiterating the fact that my daughter is a bastard, It really is the most hateful and evil word. I am a christian and I had my bastard daughter baptised as the 'sin' of having her was mine and not hers.
You on the other hand are showing the worst aspects of human nature by being judgmental, cruel and subjecting others to your twisted sense of morality. Please don't go to the Christening, your attitude and sense of self righteousness will no doubt put a cloud on what is a lovely day for a family.
I thought attitudes like yours belonged in a time gone by, but sadly I was wrong. May I just say I pity you and your narrow-minded judgmental opinion of others.
