Your post is funny for two reasons. 1. Inferring that I want pit bulls banned because I was making parallels to the two arguments and 2, b/c the article you linked to shows how common it is to let cats outside-regardless of how much it bothers people who like songbirds or hate cats. (For that matter, I suppose those who like disease-infecting rats probably hate cats being let outside as well.)
And again, I never claimed that cats should be let outside, I was saying that they are. And the harm within the risk of letting a cat out is that it might kill a vermit or a bird, or might get hit by a car or might run away. It is not that someone will kill it for their own amusement. Therefore, she wasn't asking for it or anything else when this happened. If the cat got hit by car, then you could be making that argument.
