I really liked that analogy he made. It is similar to the approach a lot of celebrities and even corporations do in regards to tweets or protests.
They can chirp all they want, but if they can't really distort your revenue and goals, then they can be ignored.
Or in more relatable terms, in school, you just focus on yours goals, whether it be practicing for the band or studying for a class, and ignore the noise of people who want to invite you to those drug parties or just generally drag you down.
