I have to say, I am always a bit [sceptical] about people who say, "okay, you might have done your research, but what if you are wrong, you wouldn't forgive yourself; avoid everything 'just in case'"
It feels a bit like bullying, even if well intentioned, especially if you have already explained that you are making an informed decision about something.
I think that is the drive of the conference reported by the BBC above, which is going to discuss why, even in the case of things where there is no evidence of damage, people are encouraged to interpret it as a serious potential danger (eg don't drink AT ALL), rather than to just be aware that there may be some level of danger, but no one has found any yet, therefore use common sense. On this subject, I have seen a number of posts in MN where people discuss drinking a couple of glasses of wine a week in terms of FAS, and I think it's really nasty , with an element of the smug and self-righteous about it.
I am not drinking this pregnancy, but only because I feel completely bullied about it by my partner, who would not bat an eyelid if he saw me eating steak tartare covered in epoisse, whilst stroking a dirty cat, and I think it's down to the DM style infantilising of women attitude referred to in the article. Rant over...as you were...
