You misunderstand flankerpilot - nowhere did Fatbus raise a racist issue - sure, he mentioned 3rd world and 1st world but that ain’t racist and certainly, in my reading, in no manner implies white/black/yellow/brown.
Your reaction is in itself racist; it certainly raises significant racial issues.
Your report to the administrators has been considered and found to have no merit.
Take a long hard look in the mirror and consider whether you yourself are not a racist Sir.
