For me it is much simpler, as I do not have 'any' religious muddling to deal with in my mind.
For me it is just 'common sense' period, the live tissue, (egg/sperm) are the making of an
embryo, 'true', on their way to create a baby, jellies kill sperm, and other forms of birth control
prevent an embryo from forming.On the day of conception, the sperm joins the egg,
same material as it was the day before, for me that means nothing, joined or not joined. I am
pro choice, I have no problem with birth control and/or 'EARLY' abortion, while that embryo
is in it's early stages of growth. I am not in favour of 'late' abortion, it is now a fetus, a baby,
and I would not interfere with that process or birth of the baby.
