:::::What POV is this Kyd?  Who's "dragging 'em around by the nose"?  Do you not WANT to make it relatively easy for our users to come to a conclusion?  Or is the point of Wikipedia to confuse readers by ONLY using scientific terms which 90% of people searching the internet need a dictionary to fully understand the meaning of?
When defining Hemmorhoids, which is the better introductory sentence?
Hemorrhoids are varicosities of [veins] in the [rectum] and [anus].
Hemorrhoids (also known as haemorrhoids or piles) are varicosities or [swelling] and [inflammation] of [veins] in the [rectum] and [anus].
You tell me.  You are trying to make us define abortion with a sentence much like the first, by supplying only the purely scientific terms (like varicosities) and not the commonly understood terms (like swelling and inflammation).  I am trying to define Abortion with a sentence like the second one, with both the scientific terms AND the commonly understood terms, so that situations like the multiple accounts listed below don't happen to our readers from a lack of information.
