I know those who defend islam have there hearts in the right place

109. Islam is a philosophy/belief system like conservatism or Republicanism

One should feel equally comfortable criticizing any philosophy or belief system that one disagrees with.

There are Islamic leaders who promise policies and enact laws that are fascist and they are supported by people who vote them into power in the name of Islam.

With respect to your other points:

1. That's true. The refugees and the terrorists are not the same people. One should not conflate the two.

2. There is a difference between "defending Islam" and "defending the vast majority of a billion Islamic people". One should be free to attack Islam as a philosophy without being seen as attacking a billion Muslim people. In the same way that one should be free to attack Republicanism as a philosophy without being seen as attacking millions of Republican people.

3. Obviously all adherents to Islam are not terrorist murderers and anyone who says so is a hate-monger. However, it is misguided to pretend that the terrorist murderers have no connection whatsoever to Islam. They plainly do. In the same way that someone who attacks an abortion clinic has a connection to Christianity even though most Christians don't attack abortion clinics.

4. Agreed.

5. What the murderers want or don't want is irrelevant. One should take appropriate action irrespective of what they want.
