There's a strange common mental image in the general public when breeding comes up. It's either viewed as a dog showing thing (breeding animals for show) or puppy mills, it's rare I come across someone who doesn't think of those things when they hear about breeding. The "breeding is cruel" seems to be a PETA/H$U$ encouraged image that if you breed animals they WILL end up in a bad home, and you're a bad person for bringing innocent animals into the world. One of my favorite things is when I'm able to talk about how captive breeding helps wild populations, encourages education, etc. with people who wouldn't otherwise know about it.
That's all I can guess at for the breeding comment. And the rest of it is something to be worked out between them unfortunately. Sucks that she thinks that BPs are such a threat, but if logic and reasoning hasn't gone through yet then it's unlikely that it'll change anytime soon.
