The song "Birth Defect" by Helmet is a commentary on human nature, particularly the tendency for people to judge and discriminate against others based on their differences. The lyrics describe a person who takes pleasure in discovering the positives in people they dislike, but then exploit and erase those positives by manipulating them. The song suggests that individuals who possess certain character flaws, such as dishonesty and a hunger for power, use these flaws to their advantage. They feed others lies and starve them of truth, keeping them in a state of vulnerability where they can easily control and deceive them. The lyrics also touch on the concept of personal biases and the tendency of people to insult and disrespect those with different opinions. The songwriter expresses a preference for being insulted by someone they do not respect rather than someone they hold in high regard, highlighting the disappointment and hurt caused by the views of those they admire. The phrase "birth defect" can be interpreted metaphorically in this context. It refers to the differing perspectives and opinions individuals possess, suggesting that these differences are innate and not intentional choices. The songwriter implies that if they do not share the same views as others, it is simply a result of their inherent nature rather than a personal failing. Overall, "Birth Defect" comments on the negative aspects of human behavior, such as manipulation, prejudice, and the tendency to belittle those with differing opinions.
