The West is just stuck in dualism, it thinks that itself is God and that the East is Satan. It's a veiled supremacist attitude.
It doesn't help that there are so many disinfo and defamation campaigns against Islam, very much a money-making business at the moment.
It only gets worse when a large majority of things used to slander Islam aren't even to do with Islam directly, such as supposed "apostasy laws". So ridiculous.
I don't know where the answer might lie but perhaps one of the reasons is that the countries that tend to make the news with regards having a large Muslim population, countries like Iran, Iraq, Saudi Arabia, etc., are often not seen as having that much in common with the Western countries where views of Muslims might not be so favourable. Other countries having large Muslim populations, such as Indonesia, Malaysia, and many African countries, just don't seem to make the news that much so as to balance out anything seemingly negative.
