You've sidestepped the obviously offensive sentence:
I will realize that mixed marriage both produces mutant kids
Please elaborate on your concept of "mutant kids".
Let me give you an idea what happens - in cases where the kid at least looks like both parents, so at least he isn't not accepted by classmates of any race.
My former rabbi explained it this way. Jewish/Christian intermarriages invariably end up in hassles over how the kids should be raised. If the kid is raised in both religions, he ends up confused. If he is raised in neither religion, he ends up with no religious values as he goes through adolescence. The divorces actually produce files over 2" thick (last I saw one) over who gets kids for which holidays this year.
Think such upbringing creates well-adjusted teenagers and young adults?
