A lot of degrees have you working hard though. A creative writing class with an insane teacher can do that. That doesn't mean you're a guru of knowledge. But I will consent that law is pretty complex, as are economics, business, accounting, finance, history, math, geology, biology, chemistry, programming, etc... (if you get the picture). Generally (GENERALLY) anyone with a degree or high level of technical expertise will understand the complexities of issues, or at least respect them if they don't fully understand them.
That doesn't people won't get mad or have a limit to which they'll then get mad. =)
I'd say a few lecture periods could easily give any reasonably intelligent person the basic gist of tort and liability, though. It's far from the most complex part of legal studies, one of the more uniform areas (in terms of across jurisdictions within the US, at least), and one of the more objective areas, largely because a LOT of case law exists and a lot of the potential hairy issues have been worked through dating back over a couple hundred years at this point. Those two facts alone make it a lot simpler than a large number of other legal concepts where many of the finer points have yet to be thoroughly ironed out by judges at various levels.
Most of the legal issues which are contentious today are so because there are rulings either being contended/considered at higher levels of the judicial system, or because they haven't even made it that far yet. That's how law really works: once legislation goes into effect, it often takes the judicial system years or even decades to figure out how it's going to work in practice. This stuff is nothing new, so when people spout off about "I'mma go sue blah for yadda yadda" without knowing what they're actually talking about, they just come off sounding silly, because the vast majority of the time a judge would just dismiss it in under 30 seconds.
