For much of it, the current generation of misguided youths have been "cut off" from the preceeding generation, and they and our nation are in peril because of it.
Our so called higher education system is largely at fault! What do I mean by this? The Bible has been removed from the classroom, faith and belief in God has been cleansed out of the textbooks -even to the extent of Thanksgiving references, attempts are being made to delete the phrase "under God" from the pledge, and on and on. Now this is deemed "neutral," however, in their stead has been substitued philosophy ( a faith or religion if you will) of another morality. Secular Humanism. How neutral is this?
An example: "What is right for you, may not be right to me," so in effect, the children are being taught to decide right from wrong according to their own consciences; and they often have none!

Dept. of Education, and of course the Scopes trial; evolution theory, so that now young men and women are after all only a few steps up from the animals, and their behavior proves it.
After having fought to preserve my life; Vietnam '68-69, and also now in civilian life, if I am removed from this life by the attempts of a violent criminal, I will go down fighting. I will not surrender, nor be slaughtered, nor give quarter to any such felons.
It's unfortunate that your uncle was not able to defend his precious, God -given life, but be sure that the killers will stand in a great court of Justice, and The Judge of the Universe, will administer judgement upon them with no revocation, parole, delays, legal manueverings, or plea bargains.
