"Christians do it all the time and Gotch picked and chose those quotes from the Koran."

What you simply are failing to understand is that those quotes from the Quran are an Open-ended command to continue with actions as set froth. There is a huge difference.

It's like the difference between a father recounting to his sons the time he killed a couple of enemy combatants in the Gulf War, and the same father instructing his sons to kill any Arab they encounter.

There is a big difference.
