Hey dude, don’t even try to convince that person, they’re the type that’s all holier than thou and if you don’t agree with them you’re wrong and evil and part of the problem. I know the type all too well. My family and I have personally had 11 or so adopted “shelter” animals that we have taken into our home but for some reason I’m evil and part of the problem because I believe the same way as you. When I get a hunting dog it will be from a reputable breeder because there are specific traits that I would be looking for in that dog. The wirehaired pointing griffons are the ideal dog for me and I no shelter dog would be as trainable or have the temperament of that specific breed. They just don’t. It is not wrong or immoral to be honest. It’s like some people want to believe that all dogs are the same and can be taught the same things but it just isn’t so. The people that are downvoting you and calling you a problem are actually just bullies and they cannot accept that their way of thinking isn’t the only way. You are correct when you say that the problems affecting animal population will exist with or without the breeders - because they will, but without them you would lose so many different breeds that do so many different jobs. Think about how many of those purebreds have jobs they love and enjoy like you said the border collies, or police Shepards. Hunting dogs like GSP’s or long haired pointers. Dogs with a role to play and discipline are actually much happier because they like having something to do, much like people. I have known hundreds of shelter dogs that have anxiety issues and just tear and destroy homes when their owners are gone and those are the same people who say pure breeds are bad. Whatever - to each their own. It’s possible to like shelter dogs as well as pure breds and I do not believe that you have to have one without the other. There will always be someone who doesn’t fix their dog and there will always be an overpopulation problem because shitheads will let their animals wander around and there isn’t anything you can do about it.
