The false Islamophobic binary between being "Bengali" v.s. "Muslim"
A lot of secular people complain about how religious people hate Bengali culture and want to LARP as Thobe-wearing desert Arabs.
But what they don't say that this inferiority complex is the direct result of their own projections of what "Bengali" culture is like; projections carried over from Colonial-era cultural imperialism by Kolkata Bhodrloks.
The projection is that Bengali culture is fundamentally un-Islamic and incompatible with organic expressions of Muslim identity (e.g., religious clothing or Perso-Arabic vocabulary), which are labelled as "foreign" and "Arab/Pakistani".
Thus, a Muslim cannot be a "true" "সংস্কৃতিমনা" Bengali without ditching such expressions and devaluing his Muslim identity, reducing it down to a worthless cosmetic label.
With many Bengali Muslims themselves internalising this idea due to education and cultural propaganda, they end up facing a huge identity crisis and feel that they cannot be "Bengali" and "Muslim" simultaneously, and thus must ditch one of those identities.
They thus end up taking the following routes:
*"Islam is un-Bengali, thus I must stop being visibly Muslim and become a 'pure' Bengali"*
*"Islam is un-Bengali, thus I must stop being visibly Bengali and become as 'Arab' and 'Sahih' as possible"*
They appear to be polar opposites, but in reality they are results of the same cultural brainwashing they've been equally exposed to since childhood.
Thus, the Arab-LARPing you see among Islamists and religious people is not purely due to religious zealotry, but also a predictable result of the chauvinistic views fed to them by the Dhaka/Kolkata-centric elite.
This is all a huge shame, since the beauty of Bengali culture is undoubtedly in its syncretic nature. People like Kazi Nazrul routinely wrote poems putting the names of Hindu deities and Islamic angels side-by-side.
Painting Bengali culture as inherently "un-Islamic" while denying this history is highly disingenuous at best and paving the way to cultural genocide at worst.
