I'm not a fan of bundling up "government" like that. After all, it is a huge, huge organisation, and the torturers occupy a space entirely different from those who help you file your tax return.
No one who eats meat can have morals stronger than those of the butcher.
Of course, that implies that U.S. citizenship is already tainted---if you aren't actively protesting, working for the government in an unrelated area isn't any worse.
