Victim Blaming of Heightism Explained

Now, just follow me for a second.
That same study found that “Tall men reported greater relationship satisfaction and lower levels of cognitive or behavioral jealousy than short men,"
OK...let's assume that to be true. And....

According to Evolutionary Psychology, “The female preference for tall partners may present an increased risk of desertion or cuckoldry (paternity by another male) to shorter men.”
Let's also assume that is true.
So here is the kicker....

The "realist crowd" (such as myself and a few others) would look at those two assertions (which we are taking as fact in this illustration) and say that "the reason short men are prone to jealousy in relationships is because they are more likely to be cuckolded by their mates". But the "confidence crowd", "positivity crowd", or "encouragement crowd" would look at those two assertions and say that "the reason short men are more likely to be cuckolded by their mates is that short men are more prone to jealousy".
Does anyone else see that? It's mostly a matter of victim blaming. If you blame short men for...let's call it "social inequity"...then that is looking at the "positive" side of things. If you point towards external forces at the potential cause for social inequality, then you're "bitter".
