In my view, if the property is empty, it's a burglary. If it's not, it's a robbery.
Robbery. A person commits robbery when he or she knowingly takes property, except a motor vehicle covered by Section 18-3 or 18-4, from the person or presence of another by the use of force or by threatening the imminent use of force.
Burglary.
(a) A person commits burglary when without authority he or she knowingly enters or without authority remains within a building, housetrailer, watercraft, aircraft, motor vehicle, railroad car, or any part thereof, with intent to commit therein a felony or theft. This offense shall not include the offenses set out in Section 4-102 of the Illinois Vehicle Code.
Let's look at the post that caused all this trouble...

How come our gun nut friends don't point to this wonderful success story? All I see is Chicago, Chicago, Chicago. Well what about Houston? All that concealed carry and pickups with rifle ranks doesn't seem to have solved their burglary issues. I guess this is the Texas miracle where you buy guns and burglars don't care and still rob you.
So including the title of the thread the word burglary and its variants (burglars, burglaries) were used a total of 4 times throughout this short post. Then the next to last word in the post was r, o, b. Subsequently a meltdown ensued. In the vernacular in the US people use the word rob sometimes for the more accurate word burglarize. Frankly I rarely here someone say I was burglarized. The expression I got robbed is pretty common and even extends to non criminal acts that do not involve violence or the threat of violence.
Obviously when I typed those three little letters at the end of my post it was a slip. Most thinking adults who aren't morons can read the other 95% of the post and utilize context clues to figure out what was being discussed. But usually when you want to have a conversation with a gun nut about anything to do with common sense gun control measures they want to spend a few months discussing "clips" vs "magazines." Do you think these people are serious? I don't.
