Did you skip over the parts where so many of the detained put their life on the line hiding and saving others? You can't just pick out 1 type of atrocity and then use that to judge everything. How were the Kapo's supposed to fight back? Many of them hid and took care of those suffering too. If you'd like to have a conversation, I'm in. If you're going to keep talking down to me, then you can move along.
Some of the Kapo's were despicable, but they were all victims. I won't paint the holocaust with this one broad brush. In any group there will be people who don't have the strength to stand up and voluntarily agree to be killed rather than follow orders.

Every time someone buys a dog from them, they are putting money in the pockets of the puppy mill and giving them permission and a reason to keep torturing these animals. I agree with GhostWolfe, 100%. I understand wanting to help the poor puppy mill dogs, but it's a perpetual cycle of torture each time someone buys on of the dogs.
