"Common sense" is a term for people who assume their ways are common. It is for those with a lesser world view, those who have not acknowledged their ways are not common, known by all, or widely practiced. At best, it is an ill-defined concept that allows people to feel better and superior to others. You have also not demonstrated how evolution forces one to forfeit subjective thinking.
A part of my academic studies includes common, everyday discourse, the way words are used, what they mean, and what lies beneath the surface of a word (or symbol). You claim I do not understand subjectivity, and while some parts of it are harder for me to understand (such as emotional reasoning, which is mostly lost on me), I have a firm grasp of what subjectivity is. I may not have much published as an author, but I would think I'd have nothing published if I was a creature of pure logic.
My decision to stop drinking Coke has nothing to do with subjectivity. This decision was based on objective facts that the high amounts of sugar are not healthy or good for the body. It is the subjective experience of a Coke tasting gross and disgusting after not having one for some time that keeps my objective decision on track.
You have not demonstrated that there are any choices going on.
The theory of evolution (I'll just put it out now, saying "evolutionist" really shows how biased your sources are, and it shows that you really don't know anything about evolution or have even that most basic grasp of its concepts: it also shows a lack of understanding in science, as there are no "gravitationist," "germist," "plate techtonicists," or "magneticist.") does not state anything about anything being chosen. There is chance survival. Though survival is very typically based on an individual member of a species to adapt to the local environment and survive long enough to reproduce, thus having a better chance at passing on the beneficial survival traits, there is nothing being chosen. It just happens.
Evolution states nothing about the debate of free will vs. determinism. Though modern understanding of genetics and psychology weaken the position of unrestrained free will, it does not render a total victory for determinism as it does not seem we live a world of fatalism either.
You still have not demonstrated, with any studies, statistics, peer reviewed material, or anything other than wishful thinking that evolution causes depression. If it did, I'm sure companies like Elli Lilly would be all over it so they could open that market up for Prozac and make even more money off it.
