I'm glad to see we're past the name calling (which I fully expected) and this seems to now be turning into a viable discussion. I know that I, as well, have gone a little "overboard" on this subject & i appologize for that.
It seems to me that the root of the debate is where does life begin? (and ofcourse our messed up conflicting laws...but i'll leave that go for now).
In my opinion, humble as it may be

It would seem logical to say
if left alone, it will develop into a human being...THAT is where life begins.
This easily rules out sperm cells...as well as an unfertalized egg (truely rediculous arguments) because if left alone, those will not develop into a human being.
I have to admit, I really didn't buy the "what makes you you?" argument either.
So please...what would your opinion be on where life begins? Not many have agreed with me thus far...I don't expect you will on this point either
