Believe me, many things concern me...
Your grammar and spelling (or lack thereof) are a concern...
Rabidity and the spewing of rote responses is also a concern...
The old lie about "People of the Book"? Odd, I wonder if anyone has investgated the veracity of "do unto others", etc.? All religions can and have and will be accused of lies, duplicity, and outright ignorance of their basic tenets. Those of any faith who are knowledgeable of the tenets of their beliefs will follow them. Those who are not will pervert the ideals to satisfy the own base motives. Several years ago, I read a book on comparative religions (something you might want look into). The book listed various fundamental texts from various religions side by side and compared the similarities and differences. There was one portion that started with the New Testament quote "Do unto others...". Oddly enough, there was corresponding admonitions in virtually every other base text or teaching of virtually every other faith. It appear humanity would be better served if the 'believers' followed the texts rather than the 'teachers'...
If you wish to keep a 'scorecard' of 'kills', keep in mind Christianity predates Islam by some 600 years and the Jewish faith predates both by couple of millenia BCE. If you tally all the 'kills' before the CE, then add all the kills there after, the Muslim world has some catching up to do; and, recall, over 70 million died in the waging of WW1 & WW2, most of them 'good' Christians killing other 'good' Christians...
I do not condone any killing for religious reasons and I am not paticularly keen on killing for any other reasons, althogh I do believe there are times when there is no choice. Religion is a choice, at its base, and to use it to justify 'ungodly' acts is itself ungodly...
