I assume you have proof of better than CD sound quality. So you are
saying HD FM is PCM? If not, please retract your statement.

It is higher quality than analog FM, which is limited in badwith. It is
capable of being "better than CD" quality if only one digital stream is used
on FM. The problem is that there is no material, other than live, to
broadcast that way, so most staitons are doing two HD FM channels.

Also, keep in mind most CDs do not sound very good, as the original
recording was significantly compressed and distorted before the pressing.

I really have no problem with digital radio schemes, but can't tolerate
anything that screws up the current analog system.

FM HD does not affect the quality of the analog signal. It may, in some
cases, cause the inability to hear ultra fringe stations from other markets.
But there is essentially no listening to such stations in such areas, so
there is no loss if nothing existed before.

AM analog has to be backed off to a 5 kHz to 7 kHz upper limit, but since
most analog radios don't go that far even, there is no loss and actually the
more limited bandwidth sounds better on many of today's radios. It certainly
sounds no worse.
