So Matt Walsh, who appears to be the sole content writer for The Matt Walsh Blog, opens a Dear Christians missive with Christians say we are a “Christian nation”. Sorry Matt, but not all Christians posit that the USA is a “Christian nation”. A much more agreeable assertion would be some Christians say we are a “Christian nation”. That is much easier to support/prove than your categorical claim.
If by gleefully sacrilegious and anti-Christian, you mean making fun of people who excoriate the ABC Family channel for featuring a drama about biracial lesbian foster parents, then yes, many world citizens would be gleefully sacrilegious and anti-Christian.
Society has always been stuck with characters like you who are convinced they have perfect insight into God’s will. Your position against biracial unions is so easy to refute, very few would waste their breath. Many of us are the progeny of biracial marriages. American military men marry Japanese, Chinese, Vietnamese women all the time. Related is a legal same sex marriage in New Mexico between two guys who would make excellent foster parents.
Perhaps you crassly use biracial marriage ONLY in the sense of Blacks marrying Whites? In any event, I would not consider you for any type of speaking engagement given your dogmatic race excluding predisposition.
