Watch the whole video. The enclosure mistake is later.
I have. What time? I think you're also taking the term too literally, it doesn't necessarily apply only to the so-named movement in England.
Enclosure or inclosure is the process which ends traditional rights such as mowing meadows for hay, or grazing livestock on common land. Once enclosed, these uses of the land become restricted to the owner, and it ceases to be common land.
And the first 30 seconds is historically inaccurate. There is no record of a passive people anywhere that was taken over by malicious masters. The record is of religiously inspired militias, who's members are happy to die for their cause, taking control of territories. That's also what you see today when states break down. Its the guys who are happy to die for their beliefs are the big issue - not the guys who would prefer to stay home and watch TV.
You're completely missing the point. The people stay home and watch TV because they are afraid of death, injury, imprisonment. Otherwise, they would be out there fighting for their freedom, not sitting at home in a cage of their own making.
