Reductio ad absurdum
The behavior of some such as murderers or homosexuality falls into the domain of criminality and for that reason alone strictly opposed with appropriate force. If deadly force is more appropriate, then so be it.
With respect to attacks upon the nation, these are acts of war by loosely grouped ideologues. Accordingly they may be dealt with both individually and collectively at our discretion. Those who harbor them now become subject to group attack. All the more reason to avoid association with such a group, just as its preferable to avoid all association with anything homosexual to avoid being jointly judged with the guilty.
