It's not ignoring them to point out that Islamists are always a minority.
They do have power in Iran right now, but part of the reason why they do is because of western hypocrisy wrt Muhammad Mossadegh. Hamas has power in Palestine too, and again, part of the reason why is the refusal of Israel to provide basic infrastructure to the people in Gaza, and their predilection for cavity searches in the west bank.
Muslims, Jews and Christians lived for centuries in relative peace under Ottoman rule. This isn't about religion.
