You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
We would like you to classify each of the following sets of argument pairs (discussing Gun Control)  into either SIMILAR or NOT SIMILAR. A pair of arguments is considered SIMILAR if the arguments are about the same FACET (making the same argument), and is considered NOT SIMILAR if they do not have the same FACET. A FACET is a low level issue that often reoccurs in many arguments in support of the author's stance or in attacking the other author's position.

Sent1: Ian brought up the point that guns make you more likely to kill a person. 
 Sent2: You can't be a man unless you're swinging a gun, and no matter how many guns you buy, it's still missing for you .
Solution: Not similar
Why? The first argument supports gun control by saying possessing guns make people likely to kill, the second disapproves it by saying men need guns.

New input: Sent1: If a gun owner knowingly sells to a prohibited felon who commits a murder with the gun, then the felon alone is responsible for the murder.
 Sent2: Gun ban = No civilians can protect themselves using a firearm = Criminals can illegally purchase guns, like tons already do.
Solution:
Not similar
