Re: Concept of honor and respect
Plenty of people don't buy into the hadith literature. Plenty of people do.
Does it really matter? Muslim governments can not even execute the most basic of Islamic laws. Go into any muslim country and the first law you see broken is that of hygeine. If muslims can't get 50 percent of their religion right (which would be hygeine), then I am not surprised if we do not have the rest of the religion correct.
However, the difference between punishments for adultery and honor killings are pretty dramatic as I've described them.
