Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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
Reason: The first argument supports gun control by saying possessing guns make people likely to kill, the second disapproves it by saying men need guns.

Now, solve this instance: Sent1: You're saying that guns should be allowed into school in order to allow some students (or teachers) to defend themselves if they were attacked.
 Sent2: Gun haters must attack people defending the right to bear arms by calling them fanatics.
Student:
Not similar
