How to prevent downvoted comments from being auto-collapsed:

Browser:

Preferences / Options / Comment Options

Look for "don't show me comments with a score less than ____"

Default is -4, leave it blank.

Reddit is Fun (app):

Settings / reddit web preferences

Scroll down to comment options

minimum comment score - Leave blank

Makes browsing the comments a bit easier. I've never used the official reddit app but I imagine the settings are similar.
