its perfectly clear that you have high blood pressure

No need for high blood pressure.

There are all sorts of conventions in News (or "Usenet") postings, so
correct or at least widely observed ands some not.

But quoting text (just a reasonable amount, to give context, isn't so
much a convention or a rule as much as a way of increasing understanding
of meaning. Therefore, to make your points, it's in your interests to
do this.

Some people post via news software (not via e-mail although they can
look similar in some ways). You choose to post via Google Groups which
is arguably more cumbersome although perhaps you find it more convenient
for your needs. You can, as has been pointed out, reconfigure this to
quote and then trim that accordingly. If you don't want to do that or
are unable, then you can cut and past from the original, or at least put
headings in square brackets or symbols to give meaning or sense to
your replies.

This isn't a nag, just a bit of advice from people who use Newsgroups a
lot to help you get your meaning across.

Hope this helps.
