Happy to be corrected for this! Deaf opinion only please

Hi all, someone posted in the ASL group about wanting to teach their baby some ASL signs, they are hearing and just teaching their baby signs. I suggested she wanted baby or home signs and the following conversation happened. I’m looking for a Deaf perspective if my opinions were too harsh. I only had hearing people respond to my preference of keeping culture and history in the language package, which is why I wanted a Deaf perspective.
