I think this is a good approach - you are aiming to help with a useful and needed service, and I think people respond a lot more favourably to people offering actual help than people saying "you are evil scum". Plus even though I think abortion isn't a Bad Thing I think that people being forced to have abortions because they don't have any other options *is* a Bad Thing.

However I think you may be disappointed by the lack of any kind of useful service offered by the university to pregnant and parenting students. The consensus of Newnham JCR was that the university is just not interested in providing such services. IIRC the graduate/mature colleges have the best provision for child care for students, most colleges having pretty much none although there is an informal network of students aiming to help each other out. I'd assume that pregnant students would be permitted to degrade if they wished to but am not sure.

(Provision for staff is much better that provision for students - but that's small comfort to a pregnant undergraduate)
