"Another cure is to not slope the ends, and bring them down along a thick
obstacle.  Six or ten feet of vertical drop is six or ten feet of drop,
whether in one small area or a 60 foot length. The response to vertically
polarized noise or signals is essentially the same, it just moves out
from the feedpoint a bit."

That sounds reasonable, so I'll agree.

"If you doubt that, consider the Pennant antenna. It works because the
pointed end acts like a second vertical, that picks up the same signal
level as the totally vertical wire at the other end. If it didn't, the
antenna would have only high angle horizontal component."
----------
I'm sure what Tom meant here is not that the pointed end of the Pennant
acts like a second vertical, but that the sloping top & bottom wires act
like a second vertical,  with their vertical components combining and
their horizontal components cancelling - at least this is how the model
shows it.
