That's funny, because the fake opposition of "emotion" and "reason" is a hallmark of a lot of double-standards used historically and in our present culture as subtle tools of misogyny.

In reality, the categories of mental events vernacularly referred to as "emotions" generally don't involve the sort of high-minded idealized abstract reasoning and executive decision-making that people on r/atheism like to espouse themselves as exemplars of despite the currency of their understanding of scientific epistemology having stopped in 1982.

The "emotions" more often than not direct our attention to a different facet of the perceptual world and might illuminate us to what values we hold, rather than the ones we just say we do. Think for a moment of someone "blinded by anger." With the proper orientation they can be capable of all sorts of brilliant inference and probability calculus to kill indiscriminately and effectively, but they may simple not consider all the consequences. What is important to them has a different scope than under everyday circumstances.

After all, "reason" can get you nowhere but from point A to point B. It can't tell you why you want to get there, or as the scottish philosopher David Hume once said "reason is the slave of the passions."

Think about highly emotional episodes in your own life, perhaps arguments with all those women you insist were emotional and thus, though it is a non-sequitor, thus "irrational." Did you really apply in every circumstance and in every facet of your life the rigid, structured reasoning, deference to statistical inference over heuristic assertion, and willingness to say when you can and cannot know something that a graduate student defending their thesis might?

Disbelief in a deity and acknowledgement of historical biology facts does not grant you the keys to the functioning of the whole human cognitive apparatus or grant license to conclude that the most difficult struggle in all of human history--the question of how do we know what we know?--can be reduced to a simple story like this.

Oh and this is a novelty account. So I'm going to say that the following image is "not-safe-for-work" and maybe make another point about the mind.

Did you get a gross-out reaction and close the link?

Now, if you did and if we follow the picture of things presented in the OP, you're being irrational. You're letting your disgust reaction dictate things for you and clinging to that emotional position rather than embracing rationality and realizing that this cubist representation that enables you to see all sides of one asshole from one perspective can do you know harm.

In reality, it further highlights that rationality and emotion are not opposed on some sliding scale. The shape of the stimulus flags your disgust reaction, nothing more.
