1. Unselfish concern for the welfare of others; selflessness.
2. Zoology. Instinctive behavior that is detrimental to the individual but favors the survival or spread of that individual's genes, as by benefiting its relatives.
You are using a scientific definition of altruism in a debate about moralistic behavior. If the motivation for an act benefits oneself, whether in the survival of one's genes, one's family, one's clan, one's tribe or one's species it is not an act of altruism in the moralistic sense of the word.
