While I'm not a Muslim, and I don't agree with most of their doctrine, I believe this post was about hatred and ignorance more than you actually questioning the validity of whether Islam is evil or not.
This is not how the children of God and brothers and sisters in Christ should ever act or treat others of different faiths. We are to love one another, not spread hatred and ignorance. We are to love our neighbors AND our enemies as we love ourselves, so I won't condone this post.
If I'm misrepresenting you, I apologize, but I don't think you were very clear with what you are asking then. If we merely pointed out the faults of everyone who is a Muslim, we are judging them, which will then open ourselves up for judgment
How would we EVER spread the Gospel and possibly convert these mislead souls by coming up to them with hatred and ignorance, as you claim they have toward us. We are to be above this world, and to act BETTER than those who would be enemies toward us. If we don't come to them in love, why would they ever come to us in that manner? Think about that for a long time before you judge anyone else. EVERY man is full of sin, and only through Christ could we ever break those bonds of hatred and ignorance. We should not judge others, even if they judge us with the hatred and ignorance as you say they do.
To be clear, I was in the US military for many years. I served in both the Afghan and Iraq wars, and I have met many Islamic followers in my time there. While there are many terrorists and people who hate us for our different beliefs, there are many more who do not hate us as well. We should never judge anyone for simply being misled, because we would never win souls acting like that. The Lord wishes that EVERY MAN would believe in Him and His Son, so that ALL MEN would be saved.
Islam, as well as EVERY other religion, may be "evil" in the idea that it isn't the truth that is Jesus Christ and his death and ressurection to save us from ourselves and our sins, but these people are simply misled, rather than being inherently "more" evil than anyone else. EVERY MAN is evil in nature, and EVERY MAN has evil in his heart until he accepts the grace of our Lord and savior, and so please think this over before you follow the hate and ignorance that you profess others have toward us. We are to be better.
