Bottom line, the world would be a better place if we all acted like decent human beings. That's what almost every faith system/religion is striving for; people acting decent to one another. That's what every diversity training that anyone ever had to sit through says. Don't be a jerk.
Many of the things on the 1957 school vs 2011 school are about those issues. People have had a history of abusing and not treating in a decent manner the disenfranchised: children, minorities, people with disabilities, and the poor. Because people couldn't be decent without a push, we have rules to protect them. If people had followed the ideals that they espouse, and lead upright moral lives, these rules would not have been necessary.
I've seen several people on this board say, when confronted by hypocrisy by Christians, well those people aren't Christians anyway. They are Christians, but they are not following the rules of Christ. Sometimes people's innate evil, cultural mindset, prejudice or hatred get in the way of the values they profess to admire. This is true of practicianers of every religion....Christian, Muslim, Hindi, Taoist, etc. It wasn't so long ago in this country that preachers said that blacks couldn't be trusted to vote. Churches in Africa are currently preaching that killing witches and/or gays is okay.
