1. The reason for the aggression, much like that among drivers of large trucks/SUV's is likely related to "compensation". In the name of decency, I will elaborate no further. If you are confused, send me a pm, and I will happily explain.

2. Why hassle the man for taking the time to proofread his own writing? Sure, no one wants to come off as a pompous-a$$, but that still beats sounding like a f@#*ing idiot (one who would criticize another for having education).
