The thing that makes it really easy to distinguish though is that facts are entangled. That ends up making lies contagious.
So when he starts talking about a government conspiracy and my surprise goes way up, it becomes pretty easy to check his facts, and realize the reason I'm so surprised is because he is lying.
As another example of the contagious nature of lies, when he lies about the projected cost of Starlink, the natural result is that anyone who thinks Starlink could be profitable is insane - it costs more than the economy, according to him, since he gave an estimate that was three orders magnitude higher than reasonable estimates. Therefore, when he moves forward to talk about Shotwell, he gets put in a situation where making his claims seem reasonable requires he continue to keep up the lies. So instead of calling her a good executive he makes sexists arguments as to to why she is so stupid. His previous lies were contagious and so he was forced into sexism in order to cover them up, because the entangled fact of a good executive having been involved in the business decisions would cast a lot of doubt on his claims.
And... it isn't that hard to criticize Elon Musk without lying? He isn't perfect, at all. I don't think its necessary for a critic to invent things to criticize rather than to just tell the truth?
