Amrapaali - sorry to harp on, but you haven't answered any of the points I raised in my post on page 15 regarding body autonomy, I would be very interested to hear your views on this. I'm afraid I don't believe that any religious or tradition trumps this. You clearly do, but I still would like to hear how you feel about it.
To answer one of your points, I do not believe that children should have to grow up in a smoking household, precisely because a child has not been asked if they are happy to breathe in second hand smoke. I say this as someone who did grow up in such a household, whose parents smoked in the car despite knowing it made us feel sick. They were twats in that respect, utterly selfish.
None of the comparisons you have come up with (smoking household - se above, scratchy clothes (no, never dressed DD in clothes like that, soft comfy clothes all the way)) hold water. And, out of interest, what exactly would happen to you or your DD if you didn't get her ears pierced - would you be shunned? Would God smite you down? I am genuinely interested.
Regarding long hair, as I battled with combing the tangles out of DD's hair today at bathtime I asked her if she liked having long hair, despite this, and she said yes quite firmly (to be honest, if I brushed it every day, there wouldn't be all these tangles). One of the reasons why I kept her hair long was because I though she would hate getting it cut, I could well imagine it would involve having to hold her down, which I won't do for hair.
Oh, and not having children doesn't make a jot of difference, I was very anti babies and young children having pierced ears before DD, and nothing has changed.
