I don't think you an ever change one's mind who is heck bent on one way only.
I have purchased the majority of the dogs I've had over the years from breeders, but I have rescued a couple as well. I tend to ignore the over zealots, and I don't let them put me on a guilt trip with the comments like 'every dog you buy, one dies in a shelter'...I can't save them all , and it's my own personal choice as to whether I rescue a dog or buy one, as is their choice to rescue only..
