First past the post protects the government

People who reject proportional representation are either people who know that democracy is bad for the government and do not want to see the government challenged or they are anarchists who want no government at all. They (people who oppose pr) are either anarchists or do not want the government to be challenged by democracy. But anarchists have nothing (practical) to lose by exposing the government to more democracy. It cannot be said to harm their (our) cause because even if voting reform is successful people will deduce its success is its freedom. Anarchists have nothing to fear from pr making the government look legitimate. The success of any system will be amount of freedom which it delivers. In fact the anti-state argument will be much more widespread and familiar due to the voting process. Anarchists have nothing to fear from pr so the only people with a legitimate complaint are people who want to protect the government from democracy. But this is a form of tyranny so we can say that only tyrants (and confused anarchists) have something to fear from pr. Pr hurts no one but tyrants.
