Nonsense.
It is time to be smarter and more nuanced in our approach. Judge each case on its merits, without bias or partial sources. To suggest otherwise is illogical and dangerous.
Ummah-ism is the cause of reckless and dangerous generalisations, not to mention foolish brainwashing of individuals that plays literally into the hands of malevolent forces that control and manipulate entities such as ISIS to wreak havoc against Muslim civilians and non-Muslim civilians alike. Ummah-ism is a self-destructive ideology. Why? Because in the modern world, it is always controlled or propagated by selfish individuals with selfish objectives. Invariably.
Just as the "Muslim world" is not some monolithic entity, neither are so called "ummah issues".
