Hello and welcome to YT.
You will find a wealth of info here but you do have to expect to be challenged and be prepared to challenge in order that you can be part of meaningful discourse re: this breed. Everyone is passionate here about the breed, either as breeders or pet owners, so sometimes opinions come across as "heated".
However, in my opinion, the most important thing to remember is that everyone here is trying to protect the breed as well as individual dogs and puppies. If you keep that in mind, I think you will do just fine.
Good luck
