Yes, I do occasionally use very long identifiers.  Normally, I do so when I
am using a lot of identifiers according to a set naming convention.  For
example, I might, in a Swing GUI application, declare an Action subclass
called:

    viewPreferencesGeneralOptionsAction

That's 35 characters.  If that's really my menu structure (that is, view |
prefs | general | options) then I really want to use that variable name.
This is not to say that I very frequently use such names, but when I need to
for consistency, I'd really hate for the language to stand in my way.

Mostly true, but I disagree with the absolute statement.

Definitely true.

Definitely true.

For those reasons, I don't agree with regularly using long variable names
unless, like in the example above, they make intuitive sense and there's
some systematic reason for that name choice.
