Do you?

No, but no one said that except you.
What I said was:

Sorry, that's not what you said. What you said was that there is
as much common mode current flowing down the feedline (at point B)
as is flowing into the half-wave end-fed section of the antenna
(at point X).

The half-wave end-fed antenna starts at point X. The feedline is
at point B. Here's what you said:

1.) You have a half-wave end-fed antenna. There has to be as much
common mode current leaving the end of that point and flowing down the
feedline as there is flowing out onto the antenna at that point. There
