RF is a multi-confessional country. There are ~70% of christians, but some regions population nearly 100% muslim... There are also regions with ~100% buddhist.
But then again, communism, was just another religionism, and it had to be replaced by something... Some new opium for the masses.
That's not quite correct... There are many differences between religin and ideological platform. Unless it is Islam as it is both a religion and a political platform with the sharia laws.
