Christians are what they are. And sometimes that means relentless and insidious. Why say your thoughts to adults who might object when you can go to children who don't yet know better?
This is worse than shameful. Any moron can see that in the end it only makes racial tensions more tight and discourages all of us working together. That's what religion does. They see the Tower of Babel as people working together and god did not like that. Even modern preachers today claim that their god wanted to keep the races separate. For this to be true you must believe their ignorant god did not know mankind would invent faster boats and later airplanes.
