first they set up an underclass by rounding up africans and bringing them over as slaves. the people who werent african didnt mind, in fact they enjoyed all the inexpensive merchandise that resulted.
then they wiped out the indigineous population. the people who werent native didnt mind, in fact they enjoyed all the lebensraum.
then, since slavery had since been outlawed, to keep the underclass vigorous they brought in chinese and treated them like pack animals. people who werent chines didnt mind, in fact they rather enjoyed getting their railroads built and laundry done for peanuts.
then they made drugs illegal and rounded up (and are still rounding up) anyone who chooses anything besides the bibles own family&society enhealthening alcohol. alcoholics and people who get high on life werent bothered.
then they rounded up the japanese and sent them to camps. people who werent japanese didnt mind, in fact they enjoyed the fire sale prices on their property.
then they rounded up the communists and destroyed their lives. people who werent communist didnt mind, in fact denouncing the competition was an easy way to get ahead in the rat race.
then they beat and even opened fire on people against the war in vietnam. people who werent against the war couldnt care less.
then they came for the muslims, the copyright infringers, the people who like raw milk, the people who like alternative medicine, the people against the wars in the middle east, the earth firsters, the animal rights activists, the occupy protesters, etc etc etc, giving themselves more and more overreaching powers at each step. the people who werent any of those just kept watching the superbowl and survivor and generally being good little consumers figuring it could never happen to them.
and then one day, when joe the plumbers favourite web forum (model railroading, stamp collecting, whatever) was all of a sudden not available because of something to do with copyright violation, he went ahead and looked into it and found out there was a way around it, and regained himself access. which according to sopa is illegal immoral job killing and downright devilish, and so they finally got around to coming for him too.
and the people who werent him, like the original poster above, cheered and said job well done.
