To a big extent, it depends on what is meant by answer. For example, I think that it is extremely important when asked by someone why I am an anarchist, to be able to answer "because I think a world free of domination and social alienation is possible and desirable". It is important to be able to answer questions however you feel appropriately.
But at the same time, a lot of anarchists develop this tendency to believe that they have found the objective truth, that they have found The Answer. This is a habit which I see as not an integral part of a healthy anarchist project so when speaking of "answer" along those lines I would say no.
