What you take as an insult, only you can decide.
As for how many take in strays and throw aways; quite a few of the members are either involved heavily in rescues, have rescued pets in our home (I personally have 3), donate time and money and products to rescues. Most here take the breeding of ANY animal, pure bred, mixed, dog, cat, etc, seriously and want to see ALL animals in loving homes rather than being abandoned and euthanized. I fail to see why a board dedicated to a particular breed should be exempt from also having people passionate and vocal about rescues.
