We had and still have our caste divisions,but even that is better than converting to Christianity.The manipulations of Xian missionaries in Kerala is alarmiong.The History of Xianity that they propagate in Kerala is worser than the History books of some Hindutva govts.
Chrisitns stay out of Hindu temple.They are only after what falls in the Hundi(Bhandaram) of the most popular temples in Kerala.Remember Nilakkal near Sabarimala temple.They will go to any extant to convert the whole of Kerala to Chritianity.So beware!
