Then how can integration exist? Surely, you must agree with me that today we live in a multicultural society in Europe and America. 52 million Muslims are living in Europe. A key factor to successful integration is to accept the culture. Now if culture is haram, and thou may not celebrate any holidays or accept anything from any culture, how can that lead to successful integration from the Muslim population? By dismissing the culture in that country, you are also distancing yourself from the native people and creating gaps which harms the society.
