My point was, there is nothing inherently polite/rude about either
posting style. However, bottom-posting IS very inconvenient to read. If
trimming is so important and bottom-posting breaks without it, why quote
ANYTHING at all.
After all, what's quoted in bottom-posting is incomplete chunks and no
longer a full record of all that's gone before (which isn't an issue
that top-posting by design has to have), which makes it even more
inconvenient, because if you need context you have to flick backwards
and forwards between different messages to get the full picture.
The arguments in favour of bottom-posting are illogical.
