It is better to stay away from them for security reasons. Intentionally to kill people does not make sense even if they are Muslims, it is better to only use self-defense.
There are more than 50 nations where Muslims are a majority (including the richest nation on earth, Qatar). There is no need to kill the Muslims, when we have the option of deporting them to any of these nations.
I also think that deportation is the best way. Murder begets another murder. War is not a solution.
