Getting knickers in a twist over slack R/T discipline seems a bit misplaced when a large proportion of the folks you talk to over certain vast regions are barely capable of speaking English...period.
ICAO Level 6, my arse.
Yes, yes, more of an argument in favour or standardization than against it, I know. But when someone is barely comprehensible due to their poor grasp of the language, thick accent, and insistence on compensating by speaking at a ridiculously fast rate, my worries are a little more fundamental than wondering if they're using "CAP13 or ICAO".
More like WTF ARE YOU SAYING, talk slower, move the microphone closer (or further, depending) and LEARN THE DAMN LANGUAGE!
