I only skimmed this, looks like typical shallow, self-help waffle.
Chads/incels may not be a binary, but they do represent two opposite poles. not many people are purely one or the other, but many people are mostly oriented towards one or the other.
I think in general, the term 'binary' really muddies the water in Current Year. binary refers to only two possible states, which is often insufficient to describe the nuances of reality. however, many things can be understood in terms of two contrasting opposites when you allow for more complexity. for example, let's say you have a magnet with a north and south pole, and metal filings that generally orient towards one or the other. some bits of metal react more strongly than others, some are closer to a pole while others are further off, but you still have a meaningful distinction between two opposing forces.
too many people assume that just because a system isn't purely 1 or 0, that no distinctions can be made, and it's a kaleidoscope of everything and nothing at the same time. I see this often, especially in the far leftist treatment of gender and sexual orientation. they fail to understand that a nonbinary system can still be a dialectic of opposites. their inability to comprehend the middle ground between two extremes is itself binary, which is highly ironic.
