Fathers do matter. We’re not just some arbitrary and nebulous “parent”. A lesbian cannot fulfull the role of a father, nor can a single mother household. All of the studies show how critical fathers (who actually father) are for healthy and happy children. The opposite is true too.
Whatever the homosexualists and the feminists say, nobody can take way the indispensible role of a father. No one. And any society which refuses to acknowledge this fact is well on the way to ruin.
