Why would believers have to force "nonbelievers" to follow its commands?
From a Christian perspective, it doesn't matter if a "non-believer" follows one, two or all of God's commandments or "sins", they are still going to hell. In other words forcing your "morality" on others does not help them in any way.
I'm not as familiar with Islam, but what good is it if someone does not believe in Allah but has to follow Allah's rules?
A side question, if your god is real,why do humans need to enforce your god's rules? Isn't your god powerful enough to do this, or are you worried that your god won't actually judge people the way you want it to?
