The NRA t-shirt is only divisive because of the media portrayal of the NRA. I fail to see how an organization that promotes responsible firearms ownership and practices is more politically disruptive than some punk kid wearing a Che t-shirt.
I see paralles between the NRA and Amnesty International in that they are both controversial organizations who attempt to do good, and such, can be targeted by politically motivated folks.
The teacher in this case.
