It is the work of the devil, IMO. People who spout about the wonders of "diversity" are quite simply incapable of rational thought and are actively seeking the destruction of society - all being pushed by worshipers of evil.
Forget who said this or where I saw it, but:
Diversity is an obstacle to overcome, not a goal to be achieved.
I don’t know the time range it took for God to confuse the languages of the people so that the people of Babel were scattered....but I have to wonder if confusion of values became the first step. The direction this nation has become one of implosion and then scattering of the people into diverse morality/values groupings! “Except the Lord build the house, they labor in vain those who build it” has become an increasingly loud spiritual exclamation point for those in this nation who are still struggling to hear the Lord’s voice!
