That would violate WP:V, actually, if I understand your statement correctly. ?!? 

 (after ec) I do not understand your question as written, so I will simply explain UNDUE in a general way. Let's say, for example, we are writing about nails. An authoritative work about nails, written by an expert on nails, and used as a textbook, or source for a textbook about nails, would get a lot of weight - we would regard it as definitive. A differing view from a nail manufacturer's website would get considerably less weight, as would a newspaper article about nails. Finally, a politician or celebrity's comments about nails would get no weight at all, unless in their article, not the article on nails. And your cousin Bob's random comments on nails in his blog not only gets no weight, mentioning them on a talk page might be considered a violation of WP:FORUM. Giving a newspaper article the same weight as an authoritative text by an expert is a violation of UNDUE - you are giving a less important source undue weight. Applying this here, then medical texts on Abortion carry the most weight; other sources carry less and less weight the farther they move from authoritative sources. I hope this helps; if this does not address your question please try rephrasing. ?!?
