libertarians aren't arrogant, their sense of equality is essentially pure. Socialism tends to judge people's "need" by their supposed social status or make policy to create a socially fair society, this bascially means people are treated differently in order to create equality, a highly dubious manner of creating a cohesive society. How are people who are essentially treated differently under the law ie (rich/poor) supposed to believe they are equal? Despite my own, often flawed championing of the poor, i still see socialism as a ridiculous and overbearing method of allocating equality. Such a philosophy is not only subjective "what's fair to you, might not be fair to everyone else", but must be constantly overseen by an overbearing and often invasive government, this goes against the heart of libertarian philosophy. Libertarians view each indivdual as equal from birth, unlike socialism which will make assumptions about people's lives given their background. Socialists make the arrogant assumption here that these people will never be able to help themselves and will move to make them equal to a child perceived to more fortunate. People may argue that no such assumptions are made, but they are even in our society, socialism fails because of ignorance and often militant backed arrogance of those in charge.
