There is a popular story among Muslims that one prophet secretly entered into a temple and demolished all the idols.
Then he left his tool on the hand of an idol. Next day the priests gone mad and started investigation who did this.
So the prophet said the idol with the tool did that. The priests gone even mad that how can an idol demolish all other which isnt alive. Then the wise prophet said so why you blind followers worship things which isnt alive, cant do things and hinted to follow the one.
So BD Muslims cant be judged for what they did. They are ignorant and mere followers of the religion made in Arab.
They demonstrated what they learnt.
