I haven't said that the state CLOSING is ever used. Not sure why you bring this
up...

> I mean resend response and FIN again.
This doesn't happen because NEW data arrives and the application has called
close().
So this new data cannot be delivered to the application. The TCP stack has do
drop it. That is why a RST is sent and the connection is moved to CLOSED.

I"m not sure which text you are citing, but are you trying to argue that a TCP
stack should drop data and not signal this to the other side? Just letting the
peer think everything is fine?
