Other than the Neo-cons, the biggest troublemaker in the world today is Religious Zealots.
Too many zealots spoil the world as can be plainly seen anywhere you are willing to look.
What can be seen as a benevolent and assuring God is now armed to the teeth and more than willing to eliminate all seen as enemies. The Muslims, Jews, Christians, and others have turned away from the principles of peace and brotherly love to a more aggressive outright attack on those that would believe differently. Substitute guns and ammo for peace, brutality for brotherly love.
Most religions today have there teachings intended to produce a favorable result to believers.
By study and diligence of a particular religion you are guaranteed a place in "the afterlife", abundant in everything not found in this life. This would supposedly be a place of peace and tranquility, and in some cases many blessed virgins with which to cavort and carry on, some say Heaven, where all is at peace and all needs are met without effort, we would not need food or drink.
Well I'm here to tell the so-called religions, you can have a lot of these things right here on the face of the earth, today, right now. First put away your AK47's, Uzis, M16's, cluster bombs, white phosphorous, conventional bombs, suicide bombers, and atomic weapons, long enough to look each other in the eyes and realize; we all want the same thing for ourselves and our children. We all want to live long prosperous lives with our families.
Instead religion has taken up arms against other religions believed to be inferior to their own.
Jews against Muslims and Christians against Protestants. They do not accomplish anything other than destruction of each other. It DOES NOT ELIMINATE the other religion, just the followers.
They all have to get used to the fact that religion aside they are all HUMAN BEINGS, not religious entities. None has more rights than the other, none have an inherited right to kill the other. Teaching such imperils us all.
So maybe this is a human condition and a condition of humanity, but until religion is put back into the place it should be, the churches, synagogues, temples, and shrines, the world will never see peace.
Bringing religious zealotry to the streets in the form of violence, brings us all down the evolutionary ladder many steps and forever condemns us to lives filled with sorrow.
