My line of reasoning behind my position is complex and can't be simplified into a bite-sized form that can be defended in a HN thread. Especially considering my original point: I'm one of the 0%; there's no chance for a fair debate.
I think it's fair to expect at least an attempt, given that you felt strongly enough to post your first comment. Without context, it boils down to "I have an opinion." Not surprising people would ask you to expand on that.
There certainly isn't if you make a statement and then refuse to say why you made it. People discuss complex stuff on HN regularly, surely the complexity of the argument cannot be higher than exists in some of the maths threads.
