There is nothing ‘Christian’ about Jehovah’s Witnesses...
Every person has the right to worship God as best he or she understands Him, and in peace. But that right ends where the rights of others to do the same begins.
I would never ascribe the doctrines of Jehovah's Witnesses to Christianity either. But so long as they are pursuing their beliefs in peace, I have to oblige them that right.
It's for the same reason which I believe Islam will never be able to coexist with western civilization.
They believe Christ is the son of God. But it ends there, and it is a cult.
