The term gets misused all the time. If you would read for the context of
what they are saying, they actually do understand the concepts of resolution
and geometry.

I thought you were going to stop responding...

While I have given both of them their ration of criticism for going off the
deep end with discussions such as these, it is clear that they have been
mostly right and you have been obstinate and argumentative. I would have
discussed the topics in a less vitriolic manner and not tolerated so much of
any of this childish bickering and name calling, but they have been more
right and you more wrong in most of this thread. You need to step back,
relax and let it go.
