It started even before, I remember most of these discussion being around in the mid nineties. They're not at all ineffective, they took hold in school and accademia and produced a generation of person deeply sensible to the topic of equity and social issues, which outrage quite easily and can be brought to bear to a wide range of causes from truly important battles to cancelling people for a shirt a friend gifted them. The delay you see is not because of the technique not being viable, it is because in culture wars you need quite literally to grow your army, as people get entrenched in their ways after a while.
