So, your contention is that Jesus wants His followers to be on the side of people who teach their children to hate by using cartoon characters.
Hmmmm.
"But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea."--Matthew 18:6
You, sir, will wish you had gotten the millstone. Repent or perish.
Very succinctly put, old friend. Nonetheless, it seems in this case, this Proverb will apply:
Pr 27:22 ¶ Though thou shouldest bray a fool in a mortar among wheat with a pestle, yet will not his foolishness depart from him.
