Race mixing ala Baal worship.  Christian Mingle is owned by Spark Networks and it’s CEO is Greg Liberman, a jew who is raking in about $40 million a year for the company. Lev. 21:15: “Neither shall he mingle his seed among his people”, which suggests mongrelization.  The KJV renders it, “Neither shall he profane his seed.”  In Hosea 7:8, the New Living Translation does not mince words and gets to the main thrust of the sin thusly, “The people of Israel mingle with godless foreigners, making themselves… worthless.”
