you are over-blowing the whole issue. All people in all the countries quarrel all the time. There is nothing special about it in US. In Poland their Polish peasants forbade urbanised women to have abortion as well. In India democratically elected ruling party, representing rural people, comes with bulldozer and flattens your house if you are Muslim seen on a public protest.
50% of people in any country have IQ bellow average. For reference US Army refuses to recruit people with IQ lower then 85, because they are impossible to train. So, 50% of people in any country are certified idiots and they have equal political rights to other 50% with IQ above average and these certified idiots want things done their way or they'll use violence. Now, when you ad education into the mix, situation gets much worse then 50/50, its more like 80/20.
