My sister just had a massive go at me on the phone because my DP and I are not going to have DD christened. To put this in context, my family are Italian RC (I would say culturally RC rather than deeply religious!) and DP's family go to a Baptist church. Neither of us are at all religious, although I would say that I'm a wondering agnostic rather than an out-and-out atheist. As far as both of us are concerned, it would be strange for DD to be christened by our choice. If she (or any future DC) wish to go to church later, I would personally be fine with that - but I would want it to be her choice.
My sister had a massive go at me, basically saying that I was a bad person because I don't go to church, that we are limiting DD's educational choices as she won't be able to go to an RC school (I'm not sure that all RC schools require the family to be practising Catholics in our area... and if they did, I don't think I'd want her to go there!), and finally that DP and I should get married because we are currently living in sin.
I was really annoyed and I told her I didn't want to speak to her again until she backs off about it. I just don't really think it is nice to criticise other people's religious / non-religious choices. I don't criticise her choices, so I don't understand why she thinks that she has the right to dictate to me? Or AIBU?
