Why stop at Hinduism and Buddism then? Why not also declare Christianity, Judaism, Animism, Sikhism, Pastafarianism, Atheism, etc. too as state religions?
We can't correct stupidity with more stupidity.
With an overwhelmingly Muslim population, Bangladesh has always been a Musilm country.
There was no need to drag religion into the constitution as the government has no business meddling with religion. Now that Islam is documented as state religion, there is no opportunity to remove it without sparking civil war.
The government should maintain radio silence on this issue for now until the population is more educated and mature in a few decades.
Anything the government says on the topic will hurt stability in this country of overly emotional, deluded morons.
