Brother, if you are refering to my post please read the ayahs we posted on the issue again. Allah created us as different races to understand the wisdom of the Creation. There is a similarity between the creation of heavens and earth and different races. Our different races are just the signs of the Creator. And in another ayah He says He created us different to meet and know each other, not to seperate ourselves. You continously ignore this part. Being proud of your physical features is a big big mistake in Islam. Nothing you have you got it yourself. Everything is given to you by Allah.
Ok, but just because Allah created us to meet and know each other is NOT a call by him for actually taking things as far as MISCEGENATION. Yes, meet each other and know each other means things like trading, tourism, exchanging of knowledge and wisdom, and even friendship, but to take it as extreme as to miscegenate actually RUINS Allah's different creations. He didn't want us to race mix, that's why he created us as separate races to BEGIN with! Don't you see?
