I humbly and politely disagree. It isn't complex its all.
Deviation from Sunnah, (injecting and) inflicting cultural based practises into Islam is the problem. People will always like people and wish to marry them and when we move away from noble Sunnah then stalking, fantascing and other Haram practises will result.
Life of Sahaba (RA) should be an example for us in everything.
