PLEASE
Yes, if there is something that can push people over the edge, is overuse of caps lock; I’m surprised we don’t see a sign like this more often. This photo was also taken at the Rally to Restore Sanity and/or Fear, and of all the weird signs of this rally, this one seems perfectly legitimate.
It’s time people learn how to properly use caps lock, because the sign of all big letters in a sentence is unbearable. People might think that if they’re using capslock, much like shouting in a real-life confrontation, it’ll help them make their point and get people’s attention. But in reality, much like shouting, using caps lock only makes you lose point to your argument.
