Yeah, West Bengal is Hindu-dominated and part of India. Hence, they are Indian nationality. Their ethnicity is Bengali.
Similarly, a Bangladeshi is a nationality. A Garo can be a Bangladeshi, but not a Bengali.

One question: Just how are they going to do that? By magic? Is it really so easy to simply "ban" a party?
How very progressive of you.
