To people who ask why complicating grammar:
Why shouldn’t we complicate grammar?
Calculators have simplified algebraic solutions, and what’s the result? Modern pupils are worse at calculating.
Computers have simplified writing and what’s the result? More and more people are worse at handwriting now.
If we simplify our languages, then our brains will deteriorate in functioning!
Humans use complex languages that’s why we are different from other animals,
Complicating English grammar will help improve our memory logic, reasoning, etc.
Simplifying will result in a loss of logic and laziness.
