For those that are a little slow on the uptake, typing in all caps on the internet is the equivalent of yelling in real life.
When Q is posting something in all caps he is pissed the fuck off and trying to get your attention.
Also note that he was in a rush, typing on a mobile device and didn't have time to bother with editing the message for miss spells or typo's.
Another indication that he has been reading the breads and decided the DivisonFags and ConcernFags needed a good bitch slap.
