If this was "people saying things I don't like" it would be absolutely fine. People say things I don't like on HN all the time, and I either ignore them or debate with them - which is how it should be.
But that's not what this is about. This is about political PR machines with unusual wealth lying to Facebook users on an industrial scale to control what they believe and how they act.
But perhaps you think lying to people on an industrial scale is ok?
