Something in this discussion thread is borked. I sense tension. I sense 
that the argument doesn't have direction and I don't feel invited to 
share my thoughts.

I'd like to figure out why that is because I want this to happen less 
often. (Right now this caused me to spend 30 minutes not writing a 
technical answer which makes me sad because I think in real life this 
issue could have been debated much more quickly and constructively.)

For now I'll go to bed, maybe looking at it tomorrow will help.
