Well funnily enough, in some sense yes, I am. I'd not wish to compare Trump and his supporters to ISIS in any meaningful way, which would be as disgusting as Livingstone's apparent insistence that the 7/7 bombers were martyrs. No matter how awful I find Trump's proposal here it's not even in the same league as the least of ISIS' crimes.
Both world views are common in as much as they are deeply divisive, though. Trump's advocacy of a blanket exclusion of all Muslims -- except those born in the US, which in some sense reveals the stupidity of the plan, as a majority of terrorism is related to native people who have gone on to become radicalised -- is, as I have said on the main thread, exactly the sort of message that plays right into the hands of ISIS. Anything that supports the narrative of a "war" between Islam and the West, independent of what the Muslim person actually does, supports that narrative and makes ISIS' position in some sense more legitimate.
We absolutely must avoid supporting that narrative. Attack ISIS, and seek to defeat them, because they are a direct threat. Muslims as a whole, though? No.
