However, taking ALL of the data into account ( from all sides ), you can start to get a clearer picture of what's really going on.
Argument to moderation. You are assuming both sides are equally trustworthy (or non-trustworthy) and are basically symmetrical in their levels of manipulation. For example, Group A might be withholding information. Group B might be providing false information. The truth, therefore, is not somewhere between partial and wrong information.
That kind of thinking is exactly what makes propaganda effective. Congratulations on being a stooge.
