I can assure you that the Madison Veterinary school is far removed from that liberal slant.
There are several intensive essays involved in the Vet school application process, and if they get a hint that you are applying because you've "always loved animals" and/or you "want to help ease their suffering", your application gets tossed fast.
That vet school is a serious business for serious professionals.
Maybe they are all like that - I don't know.
I have a feeling it's because the Midwest has such a strong farming background that the kids are already used to the animals getting slaughtered at the end of the season.
The corporations know the hardcore testing/experimentation is necessary, so they help make the school successful and also help mold the students' attitudes while they are young.
It's like being a soldier.
The rest of the world can argue about what's morally right or wrong, but you do your job, stay professional, push the boundaries, make discoveries and help mankind.
At the end of every experiment, the subjects get euthanized. SOP. Do it until it doesn't bother you anymore.
Start with mice/rats. Move up to rabbits/pigs/dogs, then on to monkeys.
It's hardcore, but somebody has to do it. (Or maybe not. But what do I know?)
