The worst thing about CSS is that a lot of people don't bother learning it, then have a strong opinion after they were forced to use it for a day.

How dare people use CSS without learning in-depth all 20+ specifications! It's an outrage!
When people have problems using a tool, you should look at the tool rather than blaming the people. People aren't going to change. You don't tell people to be more careful using a bandsaw; you install safety features.
I'm a big believer in learning new stuff, when that stuff has lasting value. However it is far more efficient to fix things, a one time cost that benefits everyone, than to ask everyone to learn the quirks of a tool, a cost that is paid every time someone new comes along.
