Problem in Assam

We all know what happened to Tripura, and sadly it might even happen to Assam in the near future. I took a walk the other day, and met multiple Bihari, Bengali and others but hardly any Assamese. I went to a place (Bengali area) where they removed the Assamese signs and demanded Bengali signs. Our people speak in Hindi while the North Indian speaks his own language. Our people dance like having a seizure while calling it Bihu. Many don't even know about our history. I wouldn't be surprised if this was intentionally by the big brother to make us lose our identity. I envy my Northeastern sister states for having the privilege of not selling lands to just anybody, good job tho. Don't turn out like us. Im a practical guy, ik language is just to communicate. I don't mind speaking Hindi to a person so that we understand each other but the problem is that its always us making the sacrifice, the South Indian is required to speak in Hindi as well when talking to a North Indian. It's like a one way relationship and one is playing the other two. The problem with us is that we are too fractured to say anything. ALSO what is up with the "but what can we do?" mentality?
