I think it's the other way around. Civil Disobedience is a type of passive resistance, but I think we're both saying the same thing here. You don't just have to do civil obedience to have passive resistance, and other techniques are equally valid. The two even go well together.
For example if a small number of people do a civil disobedience, you can quietly seed as well, so even if they're all jailed the seeding will continue.
My friend, you seem to be too young to have gone to a leech-n-lan. Those were indeed the days... yarrr...
