I am sorry my friend that you had that experience...unfortunately people can be mean and rude. I am going to do everything in my power to become a Yorkie Specialist, but as years to come, I will never lose site that people are human and you should treat all man kind as you want to be treated.
There are many responsible breeders who will help you if you are determined to breed, because they want to help you better the breed instead of damage it... So seek out good responsible and helpful breeders....those in my opinion are the ones...who want to fight to protect and love our breed...
if you get the door slammed in your face... it is probably someone in the long run you would regret ever dealing with.... at the end of the day...
Respect is a powerful word. Lean as much as you can, research and study and many doors will eventually open...
Good luck on your journey...
