They are terrorists and should be wiped from the face of India. It seems that Christianity is nothing more than their way of undermining the tribal structure. They're also fighting a force called the All Tripura Tigers Force.
Here is a blurb on them from the Tripura police website, no less.
This article also stated that the rebels are getting arms from Islamic and Chinese groups. This makes it very unlikely that the real motivation is Christian, wouldn't you say? Why would Islamic groups fund and supply militant, armed Christians?
Another peculiar thing found in this article:
"The hill tribe 'Jamatiya' worship their traditional god 'Gadiya', who is supposed to be an incarnation of Lord Shiva, in the month of March. The terrorists have issued an order that 'Gadiya' be prayed to on Christmas day instead."
Are we to understand that these "Baptists" insist that an incarnation Lord Shiva should be prayed to on Christmas?
These articles you have posted are enormously disturbing, but it is not at all clear that these are "Baptists" as we understand the term. My best guess would be that they are either some kind of bizarre syncretistic offshoot movement, or they are ethnic tribalists or local warlords who want the blame for their crimes to fall upon Christians.
In either case, it looks like criminal rebellion and sedition. I presume it's already illegal, no matter who sposnors it. This is not mission activity.
