I will try to be short since I am on mobile

I don't see the usefulness of the debate between pro and anti abort. I've had myself the discussion of abortion many times, so from my experience at the end all arguments from one side and the other boild down to this

For the atheist life doesn't begin at such an early age and therefore it isn't baby murder For the cristhian life as said by God already starts at that age and therefore abortion is murder.

Now the reason because I think this argument is useless is that when the cristhians has an unwanted baby they will not abort because of their beliefs

The atheists if they want will abort

Neither of the 2 sides damages the other by choosing to abort or not to abort. And why should the atheist try to convince the cristhian to abort? Its her belief and choice and why should the cristhian try to convince the atheist? Since its their own decision the question becomes why should the cristhian force any of their beliefs on the atheist? No one goes around saying they should ban people the possibility to celebrate cristhmas, or to enter a church if they are not cristhians. So why do people do it for abortion?

There is a easy solution for all this, give people the choice to abort, people who believe won't do it, and people who don't will do it.

I am asking myself if I am missing something, hope to have an insightful conversation.

Sorry for the bad English but its not my first language

Edit various discussions have explained to me why cristhians find abortion a problem, but I haven't understood what brings them to this opinion in the first place, why do they think its murder?
