You don't teach "communicating" first. What you do first is lay down the fundamentals. Once children's language skills are developed, which happens as their other cognitive skills advance, they can begin to dialog.
The cart goes behind the horse, not in front of it.
Your advocacy is for a world of ignoramuses. You can enjoy living there, but serious people won't be living there with you and the rest of the cavemen. We've been there. We've evolved. Atavism is for liberals, and you're surrendering.
There is NO one english language, there are many dialects.
Math is not communication, regardless of how much literallists want it.
To compare the two is to show why conservatives have such a terrible time communicating.
Your advocacy is for waiting for the ignorant to come up to your speed. They won't. There are too many dialects that you won't speak.
