Freedom fighters vs Freedom fighters

Freedom fighters fight for freedom. Fire fighters fight against fire. I want to write an article comparing people who fight for freedom versus people who fight against freedom. Would "Freedom fighters vs Freedom fighters" be a wrong title ?

Freedom Fighters vs Freedom Fighters is an excellent title. The auto-antonymous property of the phrase Freedom Fighter, whether obvious or not, immediately arrests the interest of the reader, urging them to read on.

Perhaps an alternative would be to refer to the action rather than the people:

Freedom fighting vs. Fighting freedom

This has the advantage (perhaps disadvantage if your intention is to force people to start reading the article) that it can probably be interpreted correctly on its own, whereas "Freedom fighters vs. Freedom fighters" is snappy but has no clear meaning*. It also retains some of the snappiness (at least, balance and alliteration) of the original. Unfortunately, freedom fighting sounds a little odd to me, so I don't find my suggestion entirely satisfactory.

_{* Without context I would interpret it as being an article about in-fighting within the rebel alliance freedom fighters' group.}

Very well written. A title that will catch the eye. If however, you are looking for alternatives:

Freedom Fighter vs. Freedom Buckers

Buckers meaning : Informal : To resist or oppose obstinately; object strongly: i.e. The mayor bucked at the school board's suggestion.

Just another suggestion:

Freedom Fighter vs. Liberty Terminators.
