No, They are Bangladeshi. Don't mislead with your crap thoughts. Indian Muslims are Indians only. If we wanted to cleansing Muslims, we would have done 50-60 years back same like Bangladesh and Pakistan did. Hindu Population declined 22% to 1.5% in Pakistan and 23% to 7% in Bangladesh. In India, Muslim Population increased from 9% to 14% (including 2% Bangladeshi) .
Please get your facts straight!
Most of the decline of the Hindu population in Bangladesh happened during the Pakistan-era.
At the time of Bangladeshi independence in 1971, the Hindu population was around 13%. This declined to a low of around 10% by 2000 due to the fact that the Bangladesh economy was much behind that of India during the first few decades after independence. Hindus found it easy to migrate and assimiltate in primarily Hindu India.
Since 2000, the percentage of Hindus in Bangladesh has stayed constant at the 10% mark due to the fact that BD now has a much stonger economy. The percentage of Hindus in BD has now stabilised around the 10% mark and there is little likelihood that this will change.
BD is by far the most tolerant country in South Asia to minorities.
