So, basically, my view is I don't want to support the exploitation of animals, and within reason, I will do what I can to avoid it, but it's not like it's a religion for me. It's not like I consider I'm polluted if somehow some bit of milk or cheese or something passes my lips.

There are many cases in which gifted children have done great things without special school programs. There are also gifted kids who have been to special schools and achieved nothing that has benefited the world as a whole.
