You are the one that is spreading nonsense.
You came with a poorly done study, with poor parameters and are screaming it from the roof tops about how it is "Facts". I am sorry, that is not how the world works my friend.
No one is spreading false information here but you.
Yall's is not a word. It is not in the dictionary, it is commonly used in the southern states (Which I myself also reside in) by people without much education. As it was in the 1800s when it was first spoke by uneducated members of the southern states. It is a blatant abuse of the English language.
English does not need to be your first language. A doctor, would know how to speak English and how to type it and properly.
Its okay, this is the entire, and every 13 year old Herpkeeper is a doctor or a scientist or both. I am not a Doctor or a Scientist

.
I mean you no offense. I clarified above, but will again. I also reside in a southern state where that word is used. It is one thing to use it with your friends or in text messages, and another to use it in a professional atmosphere such as this one.
The word is an abuse of the English language, pure and simple. Go get a job that requires professionalism and see how long you keep it typing yall in all your reports.
If you want to be taken seriously, and and be assumed as educated, then speak correct and proper English.
