There is only one race, the human race. There are differences between ethnic groups, but we are all created in God's image because we're all descended from Adam. I don't know anyone who seriously thinks there are no differences with gender? Except maybe some gender confused professors at my University, but that aside does anyone who is sane really think they are the same? Man and Woman, while having physical deferences, different roles, and responisbilities, are nonethless equal before God.
I don't know what you mean by Abortion is science, but I do know that it is wrong because it's killing an innocent human being.
