The difference is that the Chinese intelligence agencies abide by Chinese law and don't really pose any kind of threat to American citizens, while the American intelligence agencies engage in unconstitutional schemes (as ruled by a federal judge) to illegally spy on Americans and lie about it to both congress and the American people, murder American citizens, and can, at any moment they want, fabricate evidence to procure no-knock search warrants where a team of armed gunmen will throw flashbang grenades into the homes of journalists and political dissidents in the middle of the night before barging in with assault rifles.
And yet, for reasons that remain beyond me, many Americans remain more fearful of the former than that latter.
