How a worst habit of one culture, gets approval in other culture?

Question

For example, now dating has been approved in our society.

Answer 1

Dear friend,

Its a matter of adaptation. Since you kept dating without caring for anyone. In response to your example, the society had no other alternative accept to approve your relationship/dating. I also exemplify it , many invaders came to India with bad intentions, but they became the part of Indian society, their cultural values got assimilated with the Indian culture. So, this is not a strange thing.
