weejie, you are missing the point
It would have been insensitive of me to ask (as the first person to respond to the OP), 'have you thought about breastfeeding'? Why? Because I had no idea what lay behind her post...no idea if she was a woman, a pregnant mother, a man, a student, or indeed, someone who had a phobia about bf, or who had been told 'you can't breastfeed because of [insert random reason], or who just didn't feel comfortable with the idea....None of my biz what the reason behind her post was, and I would not dream of probing, knowing she would share if she wanted to.
So far, so sensitive.....yes?
So what did I do? I made a little light hearted comment that would allow her to respond how she wished - 'hahah, I know that, of course, but this info is for a friend who [insert other reason]' or 'yes, but I am not happy about bf, and want to ff ' and it would have been left there. A few others came back and commented in a similar vein....until you came along with your insensitive size 12s, and told me, and others off, for being 'insensitive' and it all took off from there....
And now you are saying I should have had the cheek to ask her why she wasn't breastfeeding...no, I will not ask that, because, guess what, it is insensitive.
