Looks like muslim invaders from west made permanent scar on every native hindu soul! I am going to agree with Kalu Miah about their pathogenic hatred towards muslims!
We never heard of any mass murder by muslim generals in east Bengal, although East bengal became muslim....
Sir a permanent mark was not left in our soul, but in your mind. Ours was but a temporary low from which we got back and still practising the faith of our forefathers the way they did and before that their forefathers.
Think about you, unless you were one of those Turk,Afghan,Arab invaders you are permanently bound to them,identify with them, have to glorify them inspite of the carnage they unleashed on yourself. Think where the scar is present : in our soul or in your mind.
Regarding the absence of any killings in Bengal, even if there were any you would be made to celebrate that killings as a victory of the Islamic ghazis over infidels irrespective of the fact the Ghazis were foreigners and the infidels were your own stock, the native population. Can there be any more shame than praising the killers of one's own ancestors ? I think not.
