`  == Etiology ==  I'm reverting Jjk's change of this section heading. It's true that ``causes`` is a simpler word and thus may be clearer for the casual reader, but I don't think it's more accurate. While ``etiology`` can mean ``causes`` (specifically in terms of a disease or medical condition, which doesn't work for the topic of this article), it also means ``the investigation or attribution of the cause or reason for something, often expressed in terms of historical or mythical explanation``, which works pretty well here as a definition. Nothingcauses homosexuality any more than anything causes heterosexuality. The section in question deals quite specifically with investigations and explanations of why some people are homosexual, and ``etiology`` describes the content of the section well enough.     :I am inclined to agree with your reversion. Causes can be seen to have negative connotations, where etiology is more neutral. — ·`
