God, it is hard to know where to start back here.
Lissie, just want to say you have made some excellent points
DaisyMooSteiner - in response to your question:
'at the moment the fetus has no legal rights until after birth (other than it being illegal to perform an abortion on a 'healthy' fetus after 24 weeks). Would you support a change in the law to give the fetus legal rights which compel a woman to give up smoking, drinking etc and to heed medical advice, including a cesarean section if doctors recommended it?'
No. I am completely pro-choice, and I don't think a pregnant woman should be banned from drinking. No one told this woman she couldn't drink.
However, a licensee holds a license for a reason. He or she has, as Lissie has already pointed out, been through training, sat exams, and been fully background checked to ensure they are suitable to be licensed for the responsible sale of alcohol. If they feel, in their professional opinion, that they do not wish to serve someone, then they are perfectly within their rights to do so.
I am not sure I agree that it is sex discrimination 'because men can't get pregnant'. There are clubs and bars that don't allow men or women in, and people would be refused entry based on their sex. This is at the discretion of the licensee, and as such is exempt from being classed as discriminatory.
If I had someone in my establishment who was doing something I didn't want them to, I should be free to ask them to go elsewhere and carry about their business.
To suggest that licensees should allow behaviour that they feel is inappropriate is ridiculous. It is their bar. If you don't like it, go somewhere else.
