People in power having no idea or experience in what they are voting on. Yes, I'm looking at the politicians who were saying, "DERP, I'm not one of them weirdo computer nerd-types, but SOPA is a really good bill that you should agree with and durrhurrhurrdeehurr." The fact they had not only refused to read up on the topic, but they even had the sheer audacity to tell everybody about that fact, irritated the hell out of me.
The usual bits about people who don't drive...good. In my county, where I live, we are notorious for two things: meth labs and rolling stops. I see people fly through the stop sign in the center of my subdivision as if it is not there all the time. A child (about 8 years old) was hit by a douchebag in a new mustang going 50 mph when the speed limit was half that who decided that stop signs are only there to slow him down. Naturally, his license was suspended, he was sued, etc, but the kid ended up losing his leg. And people still run through the damn stop sign. They've posted dummy cops, real cops, speed radars, everything, and they still freaking do it. It didn't help that all of these methods failed so hard that it practically made a laughingstock of our sheriff's department here. I hate it so goddamn much.
Ignorance in regards to religion and lack thereof. To put it into perspective, there was a girl who went to my old private school (I went there from K-4th grade). Her parents had drilled into her head that Halloween was a Satanist holiday that celebrated Satan's birthday of all stupid things, the Pokemon were named after real demons, competitive sports are too dangerous for honest god-fearing children to participate in, and that children who were either adopted or had step-parents were not going to Heaven. Naturally, she told everybody about all of these beliefs, not knowing any difference, and confused the hell out of a lot of kids who went to the school. Looking back on it, it seemed extremely ignorant and down-right stupid of her parents, but at the time I was very confused by it and scared (my parents had divorced when I was young, I loved Pokemon, played sports like a lot of kids, and I had celebrated Halloween since I was a small child).
TL;DR- Ignorant people in power, horrible drivers, ignorance on all sides of religion
