This is a great example of the concept of framing. When you're the only one providing the context, and you only provide the context that supports the argument you're making, you can make a lot of different propositions appear to be true, or to appear to be a lot stronger than they are. You've nicely shown why it is so important to, when reading the work of someone else, ensure that you're trying to reconcile their contexts with your understanding of reality -- the fit of the context is just as important to interrogate as the arguments themselves.

Great point! Which, of course, is also why information bubbles are so pernicious and ultimately misleading.
