My oldest kid was asked by a high school classmate the other day if he would date in someone who was of a different race. When he answered "no" and someone suggested that he had a "racist attitude" he responded that he was as far from being a racist as one could be, and that his policy of not dating other races was to show his support for "diversity" (in other words, if everyone dated inter-racially there would be no "diversity").
Not only must we use good, sound reason to defeat leftists on the intellectual playing field, but we must also drive it home with greater force and energy than they employ in promoting their insanity.
Man, that is priceless!! I will steal from the best though, and in this case, it is your son.
