I don't understand why you are taking umbrage about the use of the word "how". You might want to explain your rationale.

What I meant was, what is the rationale used by people of certain religions to think it is ok to kill people? As I understand it, Jesus Christ preached love, understanding, love thy neighbour, etc. If a Christian believes those teachings what rationale can make that person believe it is also ok to kill people? Is it hypocritical to take some of what He said to heart and ignore the rest?

I also am at a loss to understand why you sent me a polite PM at almost the same time that you decided to denounce me in the public forum.

I'm confused. But go for it! Do your darnedest! You say what you want to say and I'll express my own opinions with politeness, respect and dignity.
