Ha, propaganda videos. Lol
It does not matter if you agree about abortions. Making a law about it is bad. If you don't like abortions then don't have one.
So it is always an arbitrary line drawn from an unknown exact instant of conception. Even the first trimester boundary can not be completely accurately determined. It's always a guess.
Oh true, it is a vague line. It has nothing to do with personhood though. My only issue is the man involved has no say on the issue. Je should also have a choice about parenthood.
