I would like to point out that there used to be a great deal of, in my opinion, very unnecessary fighting over terms such as "circumcised" vs "unmutilatedcastratedstabbedpenismurdered". 
Isn't it advisable, to at least be able to use a more scientific sounding vocabulary - as in, detached from everyday speech and associations to avoid emotions. Synonyms like that are an important part of an article when stuff is looked up primarily by text search - if relevant words are missing, the article fails as a whole. Dictionaries are never complete, and neither is Wikipedia. The advantage of Wikipedia being, that we can update her ourselves as new information becomes more widely available. IAR2TR.
