While true, its a bit odd of a statement. The following statements are also equally true:
Having no problem with deforestation does not make you "anti-environmentalist".
Having no problem with Ku Klux Klan members does not make you "anti-tolerance".
Having no problem with murder and theft does not make you "anti-government".
Except... if you are helping others in deforestation, the environmentalism movement will dislike you. If you are helping the Ku Klux Klan, the tolerance movement will dislike you. If you are helping murders, the government will lock you in.
So why do you label FSF as zealots for disliking actions that helps those that want to threaten users with lawsuits and prevent new versions of software for being used, shared or modified?
