It is unfair and inaccurate to label an entire community as "selfish." Communities are diverse and made up of individuals with unique beliefs, values, and behaviors. Generalizing an entire community based on the actions of a few individuals is a form of stereotyping and can perpetuate harmful biases.
Like any community, the Bengali community consists of a wide range of people with various personalities, backgrounds, and perspectives. Some individuals within the community may exhibit selfish behavior, but it would be inappropriate to apply that characteristic to everyone.
It is essential to treat each person as an individual and not make sweeping judgments about an entire community based on the actions of a few. Instead, it is more productive to focus on promoting understanding, empathy, and cooperation among all communities.
