It seems to me that you have entirely discredited yourself. You confidently make claims about the Russian language but don't even know the most basic thing about the point you were making.
It takes tremendous study to arrive at a conclusion and your inability to get _basic_ details correct, that your narrative depends on, betray that you have not done that study.
You are not my conversing partner. You are simply someone who emits nonsense onto the internet and people should be aware of you willingness to confabulate reality.
If making one mistake discredits the entire take, I'd hate to be your conversing partner ever.
