Religious Jews main mission in life is to perform as many Man to G-d and Man to Man Mitzvas as possible in his/her lifetime.
In Islam, Muslims perform their “Mitzva” by killing (or being killed) in their Jihad against the “nonbelievers”. So, their function in life, is death. It's that simple. They are doing what they are programmed to do and they do not hide it.
The West lives in denial...
That’s why I hate hearing conservatives talk about “radical Islam”, as though there is some kind of “moderate Islam”. There are moderate Muslims, people born into Islam who are not particularly religious, but there is no moderate Islam.
