Why in islamic countries all the rights were denied to minorities? They can also give all the rights to minorities. The only reason they want only islam there. No minorities in islamic countries can raise their voice also.
But in non islamic countries we can see muslims(terrorists) creates problems by mounting bombs everywhere. More than them you can see dangerous fellows like gladiator who justifies this things.
My advice is why can't they advice islamic nations these things and tell them why you are identifying everything by islam only. Allow every relegion and guarentee their rights.
