The problem that eastwatch mentions pertains to Bangladeshis worldwide, including himself. That is a problem of ignorance. Whether secular or religious, no Bangladeshi community has excelled anywhere in the world. What is the economic and social profile of Bangladeshis in any "secular" kafir country of the world? The question is: Why could not the secular BAL and its minions, or its followers abroad, attain the highest known levels of scientific learning in any field anywhere in the world?
As for rants about Afghan Taliban, do not BS like ignorant Indians without knowing a thing or two. It was these Afghan Taliban that eliminated drug/poppy production in Afghanistan, something that NATO/USA invaders have successfully reversed. Not only that, Western terrorists make bogus claims like that is the sole source of income of Afghan Taliban. Once proven wrong, they change tune and claim the only source is 'protection money'. Then, they change tune again, and claim it is Gulf Arabs that finance the Afghan Taliban. In short, the West is known to lie through their teeth.
The truth is no segment of Bangladeshi society - expatriate or resident, 'secular' or 'religious', 'educated' or 'illiterate' - are masters of their trade. No religious scholar or political party ever preached about the concept of Islamic law, let alone its implementation, to the public regularly. The extent of their 'fatwa' goes as far as praying five times a day, doing 'good deeds' (vaguely worded), respecting elders etc. No word on banning interest, no word on implementing Islamic Sharia in its entirety.
Likewise, the seculars achieved nothing. Usurping money, extortion, nepotism, grabbing tenders, incompetence, corruption, and the likes characterize their reign. Again, what have secular Bangladeshis achieved in science either within the country or abroad? Why is Bangladeshi scientific knowledge, industrial capability, and technological achievements so low, compared to other developing countries of similar levels of development and population? Both Nigeria and Pakistan are ahead of Bangladesh in scientific publications, economic indices and so on.
Do not make excuses. The problem lies with your ignorance.
