The Left and The Right- Reversed?

In the political spectrum, it's well known that liberals are known as the "left", and that conservatives are known as the "right". However, the left brain is associated with conservative traits, and the right brain is associated with liberal traits, as this link and a picture will show:

As the picture shows, the left brain is associated with these things: order, logic, math, analytics, detail, and linear thinking. The right brain is associated with art, colors, music, the big picture, randomness, emotion, and creativity. The vast majority of the things listed as right brain characteristics are things that are ruled by Neptune, and as this blog shows, people with their Venus (economics) and Moon (culture) in aspect to Neptune but not overcome by the North Node lean to the left. For the left brain, the things listed under it are things associated with the Earth signs, which have a reputation as being the most conservative in astrology (Venus rules Taurus, an Earth sign). Some people divide the halves of the zodiac as the left hemisphere, but if that was the case, the sign of Pisces, which is associated with the majority of the right brain characteristics, would be associated with the left brain, as it's the 12th sign of the zodiac, and Virgo, which many of the left brain characteristics are associated with, would be associated with the right brain, as it's the 6th sign of the zodiac. That wouldn't make sense.

With this knowledge available, is what we call the "left" actually the "right", and vice versa? Maybe. The liberal people I know fall heavily into the right brain characteristics, and the conservative people I know fall heavily into the right brain characteristics. This is why most celebrities lean to the "left" as actors/actresses and musicians are very creative people, and why Libertarians are associated with the "right", as they tend to base their lifestyles around logic and self sufficiency, which are left brain characteristics. This left and right brain divide also supports something I've noticed in person, which is that left brain conservatives and Libertarians tend to be much more rigid than their right brain liberal counterparts, who tend to be much more open minded and loose in person.

As for the research in this blog, I'll still label liberal astrological impulses as "leftist" and conservative astrological impulses as "rightist" in order to prevent confusion among readers, but this knowledge is something that should really be considered, as it would make a whole lot of sense to label liberals as the "right" and conservatives as the "left", based on the left and right brain characteristics.
