If it works in an "incorrect manner", does it damage the original author? Is the author harmed if their software is modified to help run and promote a detestable organisation?

I think people normally read the author's names on the "cover".

That may be the case, if you purely want to spread your opinion. It's not a Free licence, though, is it? It doesn't help people to build upon your work, unless you allow "verbatim copying in whole or part with attribution".
Despite its name, the GFDL appears not to give the full freedom to use, study, modify and redistribute. After thinking about this some more, I think Debian are probably correct to classify it as non-free and FSFE may wish to consider asking GNU to fix their licence, even only the name.
