Because there is context beyond "simple facts". A "simple fact" doesn't necessarily mean what the person presenting it thinks it means. There are other factors that go into this "simple fact" that may or may not be mentioned by the person presenting it.

So while the fact itself may be true, the causation could be different from the implied causation by the presenter. For example I'm sure you noticed that women skew younger on this survey. If people are earlier in their career perhaps experience and culture matter more than pay. People later in their careers have families to worry about, so they want more pay and care less about culture and languages.

I'm not saying I'm correct in this assessment, but what I'm getting at is there needs to be greater context around "facts" beyond the first thing that pops into your mind. Facts can be twisted in many ways to hurt people, be more critical of the things people say on the internet.
