They never celebrat, they always try to convert. They are given budget for that. Like there is a proverb, " Naya Mullah jyada pyaj khata hai", convert Dalits try very hard to convert more Dalits to come in the good book of their masters. None of those Goras have become Krishna devotee for a bag of rice.
Indian Hindus who go to these western countries and Indian Sikhs convert the demographics of Western Christian and Muslim Gulf Nations too! They just do it in another way!
