In a healthy society, elderly people are treated with respect, even reverence. This kind of attack shows how far our culture has devolved. And Im sure there are plenty of liberals who will defend the savages who beat Mr. Shea. A part of their thinking, though they arent quite to the point of admitting it publically, will be that an 84-year-old man is a useless mouth, a person of no value who will probably die soon anyway.

I believe there are still plenty of people who respect elders. Just not THIS particular segment of society. Their values, if any, are quite different from the rest of civilized society.
