Deeming something abnormal that has been around for all of recorded history belabors the definition of ‘normal.’
And "normal" -- from the root word "norm," as in the statistically most common -- has not changed, even though the pro-homos would have you believe it has.
Spark, ALL abnormalities have been “around.” Disease is universal. Deformity is very common. Malformation and malfunction occur everywhere. But the fact that they are common does not make them normal.
To say sexual perversion has been “around” for all of recorded history, is not the same as saying it has been considered healthy, lawful, accepted, or honorable.
Every offense, crime, and disorder has been “around”, across the centuries and the civilizations. That’s why successful civilizations have customs discouraging them, interventions correcting them, and laws prohibiting them.
