Hi zuni
i can only speak for myself here but i don't see conflict as a motivation to continue a thread..
a difference of opinion or belief or knowledge now that is a fair exchange if done in a respectfull manner
personally i enjoy a lively discussion of what i think i know vs. what someone else thinks they know
that said
when i come across someone posting that i you can not answer because they don't respond to the topic at hand but jump on their soapbox and try to beat the other posters into the ground with thier harangue
...then i just don't read what the person has to say anymore.. ever
they can type their little fingers off but i don't engage..
that's my solution..for what it's worth
