Hey, step off. Some countries -do- follow law based on the islamic interpretation. While muslims are not allowed to alter laws based on what the quran would outline them doing, they ARE allowed religious freedoms outside of that scope.
Killing animals without stunning them isn't "inhumane" any more than other slaughter methods. I'm a vegan personally, but I am fully in support of brothers and sisters who choose to follow a meat-eating halal diet.
No, I don't know what some muslims are like. You don't see me "making a musical" the countless times I've had people push and shove at me, call me names as innovative as "terrorist" and "go back to where you came from", and as a personal favorite, "sand ******". You don't read news articles about every time I've had someone pull off my hijab. Nobody has to know about the broken windows and spray paints and all sorts of enjoyable attacks local halal restaurants face, never mind someone throwing a whole dead PIG in the parking lot of my masjid.
