"Call a life starting where ever you want but don't tell me where you think it starts for me untill you have undebatable back up to prove your position & not a minute before that."

Again, you are placing the burden of proof on the wrong party. The side that wants to extinguish the life should be the one with the burden of proof that it is not a human before they are allowed to kill it. All the rest of our legal system works this way.

You should be the one with the "undebatable back up" if you wish to extinguish the life.

If you think that more contraception should be available, fine. Fight THAT battle. But don't tell me you should then have the right to extinguish life until such time as you prove your case against the unborn.
