I think its easy to use religion as an excuse.
I dont think organized religion is the evil...I think its some of the people who are. To be quite honest, I cant think of a single organized religion which believes in fighting wars or violence etc as the means to resolve issues...
I can say without reservation that Christianity is the result of great deception, an early and very evil organized criminal conspiracy that has damaged this planet and humanity more than any disease more than any natural disaster. It is a grave danger to humanity to tolerate it in any form. It has a long exhaustivly chronicaled history of warfare conducted to resolve issues as you put it. It has also conducted warfare to indescriminately butcher it's enemys and pillage nations and cultures unnumbered. As if that wern't enough to condemn it to it's own version of hell it has also fed on the weak and the poor since it's inception. It has no purpose other than to pervert the works of man and defile nature by it's very existance.
