I'm actually quite serious.
Are you really refusing a lower altitude while on a vector?
If I lose comm while on a vector, the MSA is the first thing I will check. There is no way I am just going to start climbing without checking the chart (a 2 second procedure), as some MSAs are broken into several sectors, all with different altitudes - a very easy thing to mix up.
As for SA, I agree it is important to know where the high terrain is, but I have never heard anybody refuse a lower altitude because it was below MSA.
I understand what you guys are saying, and if the other pilot I am flying with wants to brief it, so be it. I really don't care. I'm just trying to understand what I'm missing.
