It's not just one thing. I can easily whip up a list:
- Cars - they strangle out the city and make our urban communities dystopias
- MS Office - I can mostly avoid it, but every time I have to use it, WTF?
- Java - the syntax is fine. It's the whole universe of build/config/versioning tools that gets me
- Pure Capitalism - I'm ready to protest the hell out until we get some democratic socialism
- First Past the Post Voting - It just degrades into a two party lockdown
