"GRABBER will be an appeal to emotion. “Won’t someone think about the children,” they’ll cry, while completely ignoring the statistics on homicide or inefficacy of gun control policies"

I would disagree with this part. Grabbers tend to use lots of statistics (from www.statsthatprovemeright.com) while ignoring principles.
They often try to take the pragmatic position "look i get the 2nd amendment but Japan did bla bla bla an Australia did X Y Z"
