Sure it is. The woman is pregnant with a entity that is the result of the fusion of a human egg with a human sperm, giving it the complete set of human DNA. Your denying the humanity of that which with the woman is pregnant is delusion of the highest degree.
Abortion is wrong, but not for reasons you hold.

Idiotic.
