I believe firmly in the concept of "educated idiots"... I've seen people that can spell correctly and use grammar perfectly who are beyond help socially and lack any form of common sense whatsoever...
This is part of being in the human race, and no matter what you do, there will always be people who, how shall we say... IRRITATE THE HELL OUT OF OTHERS...LOL
I just try not to be one of them :-) And for those who are, I have this unique ability called selective hearing to tune them out...
Just take them for what they are, and don't worry so much about it buddy... Anyone with common sense can identify the idiots and we all know who they are.
