Hahahahaha, I too am familiar with that "uh-oh" of TNR - when you simply cannot bring yourself to return a formerly sickly kitten that you've helped nurse back to health, back!!
Good colony caretakers feel just as bonded to "their" cats, by the way, as many ordinary pet-owners. Given the proper support, a caretaker will not only provide regular food and care, but they will also get sick-pet help for the cats if they need it (most never need it).
It's very unkind of people to think that condemning feral cats doesn't hurt PEOPLE, too. Teaching children that destroying animals "works" is simply wrong, and leads to many other social problems, and children (and others) are usually smart enough that when they DO learn about TNR, they think pretty badly of those who chose death.
Kindness, Compassion, is the way
