Final answer:
Guitar's argument mainly suggests that all white people are inherently capable of committing hateful crimes, a stance that is less about the influence of money and more about a generalized, innate predisposition.
Step-by-step explanation:
The excerpts provided suggest that Guitar has a deeply rooted belief that white people are capable of committing horrendous acts of racism and intolerance due to an inherent nature, rather than money being the driving force behind supremacist actions. This can be interpreted as Guitar holding the view that white people, as a whole, exhibit these tendencies not just because of financial greed, but due to a perceived unnatural characteristic of the white race itself.
Guitar's argument, as inferred from the context, leans heavily towards the idea that every white person has the potential to commit hateful crimes, a generalization that suggests a pessimistic view of racial relations and morality among white people. In contrast to Milkman's stance that there exist good, naturally inclined white people, Guitar is skeptical. As such, he does not talk about the influence of money and white supremacy anymore because he seems to believe that the issue of racial hatred transcends economic incentives.
Therefore, based on the information provided, the main point of Guitar's argument aligns with the first option: White people are inherently evil and capable of committing hateful crimes.
