First, I'm not 20. Second, no matter my age, I have more experience in this breed than 99% of the people on this forum. I've probably seen more German Shepeherds, of all sorts of lines, in the short time I've been "in" the breed, than most people will see in their lifetime. Not only have I seen them, many times I've also spoken to their handlers and breeders at length about the dogs and about why they do what they do.
The arguments I'm talking about are the one's that are just "this is how I want it and that's how I'll have it." There is no basis for it. It's just what it is. If, as a GSD owner, you believe that the breed is supposed to be 120lbs. You are uneducated. There is no other word for it. Maybe delusional? But really...there is no other way to explain why someone would search out an OS GSD other than PERSONAL PREFERENCE which is not based in any sort of historical fact. I don't care that people do that, but that's the only word for that opinion. If you can't back it up with anything other than your own extremely limited experience with GSD (usually the GSD they grew up with), it's not really a valid fact. So it's just an opinion, and you shouldn't really guide other people's decision making with YOUR opinion. Especially when it comes to something way bigger than you, like the GSD breed.
The point of having a BREED is so that things are as close to BLACK AND WHITE as possible. If it wasn't, you'd just have a bunch of mutts.
I hope that one day you decide to take your dog to actual protection training, or maybe agility, or maybe some other sport...and it performs like you want. Or maybe, you'll take it to one of those venues, and the dog won't do it. You'll understand what I mean then.
The way breeders make "pet dogs" these days is simple...take out all the drive. Dogs without drive are safe, they don't make their own decisions, they don't want to do anything period. My point originally was don't quote Max, or some long lost literature on the origins of the breed if you're going to completely discount the fact that this was always supposed to be a working breed. If you want to use Max to back up your point that "OS GSD" were acceptable, you should also accept the SV, you should accept Schutzhund as a breed test. You can't just accept the parts of what he said that you like, and dismiss the parts that he said that make you do more work to breed dogs.
