I didn't say this didn't create a difference. I said the reason given was not just to create a difference. God didn't give the laws just to create a difference or else it wouldn't matter what he told us to do or not to do. There must be sensibility behind what God told us not to eat. He didn't just decide on some random meaningless restrictions simply to make a difference. It is no coincidence that the nation of Israel were the healthiest nation.
Actually, He did.
"For thou art an holy people unto the LORD thy God: the LORD thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth. The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people: But because the LORD loved you, and because he would keep the oath which he had sworn unto your fathers, hath the LORD brought you out with a mighty hand, and redeemed you out of the house of bondmen, from the hand of Pharaoh king of Egypt." -Deut. 7:6-8 (KJV)
God promised to Israel, not the Gentiles:
"Behold, the days come, saith the LORD, that I will make a new covenant with the house of Israel, and with the house of Judah: Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD: But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people...And they shall be my people, and I will be their God: And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them: And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me." -Jer. 31:33, 32:38-40 (KJV)
Notice these words were not said to Gentiles, Jeremiah took these words to Israel.
Yes my friend, God certainly did not only place the Law to differenciate the Hebrews from the Gentiles, but God also nationally elected the Hebrews above all others. He set them apart.
This created a difference, a difference created by God.
