They will frame it as being white Christian colonialism enforcing their evil moral values on the world. They can even give examples on how it is accepted in some cultures and who is to say if a culture is better or worse. We already know that according to leftists any culture that is white or Christian is evil and needs to be removed as an influence so it's not hard to go from here to full pedophilia.

If the time comes I just hope there are still enough good men that care enough to fight it. If anything it may finally unite people regardless of ethnicity or religion.
