Never automatically display HTML in an email

Hi,

I use Gnus for email.  How can I make Gnus never automatically display
HTML in an email?  I'd also like the option to view the HTML in Gnus if
I want to, but that isn't a hard requirement.

Here's what I've tried so far, with limited success:

* Disable automatic display of HTML (as suggested in (gnus) FAQ 4-6):

    (setq mm-automatic-display '("text/plain"))

  This did not work; sometimes Gnus would still automatically show me
  HTML in email when it appeared in a multipart message.

* Ensure that Gnus does not accidentally render HTML in-line when it
  appears in a multipart/related email (as suggested in (gnus) MIME
  Commands):

    (setq gnus-mime-display-multipart-related-as-mixed t)

  This did not work (even after adding "text/html" to
  mm-discouraged-alternatives); Gnus would still automatically show me
  HTML in email when it appeared in a multipart message.  I also tried
  the variations of this variable
  (gnus-mime-display-multipart-alternative-as-mixed,
  gnus-mime-display-multipart-as-mixed), but the results were the same.

* Ignore HTML entirely:

    (setq gnus-ignored-mime-types '("text/html"))

  This DID work, actually.  However, it's overkill for me, since it
  makes it a little difficult to view the HTML in Gnus or save it for
  viewing in another program.

  In addition, even though this effectively removed HTML parts from some
  emails, I was surprised to discover that for multipart emails, I was
  still able to press the button for the HTML part and view it in Gnus.
  I'm fine with that, since it still meets my requirements, but I'm
  surprised because I expected that Gnus would not even let me view the
  HTML part in this way.  After all, I thought I had told Gnus to
  totally ignore HTML.  Is this the intended behavior?

If anyone has any tips on how to make Gnus never automatically display
HTML in emails, while at the same time giving me the option of
displaying the HTML in Gnus if I want to, that would be really nice!

Thank you,
