That's a REALLY tough question. I guess for me it would be abortion and the death penalty. Both are murder, yet both are legal just because they're called something else. Government sanctioned murder is still murder, no matter what they call it.
Alot of smokers also piss me off. So many of them want to have the right to smoke anywhere they want, but why the hell should *I* have to pay because they're too ignorant to avoid something that causes cancer, bronchitis, emphysema and other horrible things? If I get a case of the flu I'm not going to run out breathing my germs all over 200 people at the mall. That's just RUDE..
Drunk drivers are also EXTREMELY offensive to me. I can't believe these morons think they have the right to put the lives of other people in danger just because they drank too much and didn't have the intelligence to bring along a designated driver or take a cab to the bar and back.
I'm also offended by lazy fuckers like this guy at Wal-Mart the other day. We had a headlight out so we bought a bulb, and since I am 9 months pregnant we didn't want to get a ticket (especially if I happened to go into labor!) so we stopped to change the bulb in the parking lot. We had a spot right by the doors (no, not handicapped, lol) and this guy stopped right behind us and waited on the spot. He waited and waited... other people couldn't get past him... people were blowing their horns...
He GOT OUT of the car to come tell my husband that he was waiting on the spot. When he saw that he was fixing the light he said, "I was waiting on this spot. I didn't know you were fixing your car." Then we walked all the way back to his car (which was STILL blocking traffic!) and he drove to a spot that was only 3 cars down.
Now get this!!!
He saw my husband finish with the headlight and get into the car, so he BACKED OUT of the other spot (remember, only THREE CARS DOWN) and proceeded to drive ALL THE WAY AROUND the row to nab the spot we were pulling out of. He could have been shopping for at least five minutes by the time he managed to park.
HOW FUCKING LAZY CAN ONE IDIOT BE????
OMG, it's just astounding what the world has become.
