If they cannot distinguish between the doctrines that is just laziness.
No, not really. It's not the doctrines, it's the fundamental adherence to faith in a magical, omnipotent being. Laziness is saying "it's God's will" to questions that you don't know the answer to.
Why did God let 6,000,000 of his chosen people be slaughtered? It's his will.
Why did God let Priests sexually abuse children and allow the Catholic Church to cover it up? It's his will.
Why did God let a giant Hurricane destroy New Orleans? It's his will
Why did God let a woman get raped? It's his will
The laziness is on religion's side, relying on faith to explain away questions you don't know the answer to, either because you're too scared, lazy, or stupid.
Islams religious views are the government and society. Get the difference there?
No. Christians seek to impose their religious views in government and society all the ******* time.
