If OP had actually read the fucking Bible, they would be able to see that God used the division of races/tongues as a punishment, not some goal. They were building a tower to reach the heavens and be secure/famous.
Jealous, being the terrible god he is, went "Fuck that. I don't want humanity doing things" and scattered them/confused their tongues. Keep in mind, this is post Adam and Eve leaving the garden and post flood. Nations and the different ethnicities are already laid out by Noah's sons splitting up. This is just Jealous living up to his name.
Using the punishment for "God's Plan" is asinine. It would be like saying "God wanted people to suffer, die, and go to hell, that's what he made happen after Adam and Eve ate the fruit."
And, my guess is the OP is Protestant, because they never seem to understand what the Pentecost was all about. You're not gifted "diverse tongues" it's people can understand you no matter what you say. So that gibberish people babble on stage? Can't be speaking in togues by definition.
