What are you even talking about? Indians carry their culture/traditions everywhere they go. No one is "throwing it away". You are talking as if Indians have started to emigrate in just the past few decades. Indians have been navigating the World for the past 6000+ years at the very least (recorded history). The word "Navigation" is itself a Sanskrit word "Nava gatih". We are an Ancient Civilization and the oldest surviving Civilization. Everyone else either converted and destroyed their own civilization or were destroyed by invaders.
