Respect for people who have some physical or emotional problem.
Respect for people who have a different faith than you.
Respect for the elderly--to many or just forgotten.
Respect for the veterans of Vietnam and all wars. I say Vietnam in particular because the soldiers who came home were not treated with respect. There were no parades. They were the target of ridicule and anger by many. As the Kenny Rogers song Ruby notes, "It wasn't me that started that crazy Asian way, but I was proud to go do my patriotic chore." These are the lost veterans. They did not start the war. Most were drafted and had little choice. They just did their jobs.
