Oh dear! And I thought that FF and I were 'debating' ('arguing') these issues perfectly rationally and politely - which I know he agrees is so.
The word 'argument' does not in itself imply belligerence, antagonism or rudeness; it is simply the advancing of views and, if necessary, the rebuttal of others' views. A debate is an 'argument' - as is the reasoned case put forward in legal proceedings (in court or otherwise) by which one tries to convince an opponent, or judge. Colloquially, an 'argument' often means a heated disagreement, possibly with physical violence, but that is not the primary meaning.
I should be interested to know from Russ the etymology of both 'transvestite' and 'crossdresser'. I don't think he means 'etymology', i.e. the derivation of a word and its possibly changing meanings over time. Clearly, both words have a very different root. ('Crimson' and 'carmine' are very similar shades of red - identical to many people - but have totally different etymologies.) Yes, in common perception TV and CD mean more or less the same (or indeed exactly the same) but that is a view born out of ignorance (rather than proven by reasoned 'argument'), as both FF and I have been trying to demonstrate, uphill task though it may be. To repeat (briefly) in terms of the male gender: a TV aspires to be a woman in clothing, appearance and behaviour (whilst remaining a genetic male); the CD merely wears (some) female clothing but without trying actively to 'pass'. A useful and valid distinction, surely, even if a believer may be accused of seeing his leaves as blue ... or maybe as crimson ...?
