They make sense to the type of people who like to talk shit to waiters (knowing there will be no come back)
or over the telephone (same reason).
I always make a point of fully disclosing my novice status, as a grower.
This can be misinterpreted as "I will accept anything I am told".
When I disagree with someone who considers themselves more experienced than me
it leads to indignity.
When I go further and articulate WHY the more experienced grower is wrong,
and I post links to expert opinions that support my position.
Members, like this guy, become bitchy and make a point of joining every thread
where they can attempt to insult me.
99% of other members can recognise the situation immediately
so I am confident that most unbiased contributors
were simply ignore the immature attempts to derail the thread.
Like all children this guy will have a tiny concentration span
and it will take very little time, of ignoring him, before he moves on
to find threads where his provocations are not ignored.
Some people have lives so sad that any kind of attention pleases them, even insults.
People need interaction with others.
A few characters are so alone that this interaction is provoked with childish tricks and comments.
It's really very sad, when one thinks about it.
