Helluva list---and that just scratches the surface.
What will it take for some to realise that Islam is a REAL LIVE threat?
I dunno! (Maybe it is we who are mistaken, I would love to hear that I am worried about nothing!)
Sadly, I think the answer to your question is FEAR. To admit the truth requires courage.
Another attack with casualties on American soil (which I daily pray to the Lord against...); one conducted by Muslims hitherto considered "moderate" and "mainstream".
A general declaration of war by the same parties, preceded perhaps by some pretext for them to be generally massing in the streets, marching to demand redress for, or in protest of, some alleged ill-treatment or exaggeratedly egregious violation of their "rights"...
Obviously it is not enough for some that, in one Michigan city, (owing to the muslim majority on that city council) five-times daily calls to 'salat' - muslim prayers - are broadcast audibly throughout the city over a public loudspeaker system...a gesture which would certainly not be similarly suffered American Christians or Orthodox Jews to practice.
