The key word here is "see". The problem is that we mostly see what we're primed to notice—which is basically whatever we most dislike—and we simply don't see (or don't weight as heavily) all the cases that don't feel that way. This creates a feeling of "every" or "always" (see https://news.ycombinator.com/item?id=23835843 in this thread), which is a true statement of what you've seen, but only because your seeing is extremely conditioned by your passions on the topic. (I don't mean you personally—we all seem to have this bias.) People with opposite passions see literally the opposite picture. Moreover, the degree to which the picture you see feels unfair and unbalanced is a function, not of the raw data stream, but of the intensity of your passion, regardless of which direction it points.
For evidence, if you search my comments you'll find examples where I've admonished users for flamewar in the opposite direction, as well as for flamewar on other topics, including nationalistic flamewar about other countries (India is probably the second most common case; Russia was up there for a few years and still flares up at times).
