Then please present why the bible is objectively not against abortion.

Your insistence that christianity is not open to interpretation on this issue is objectively wrong, as clearly there are others who do not interpret as you do. You cannot argue against this.

If this is genuinely objectively not what the bible is teaching, then christianity as a whole is a sham, because that is the prevalent teaching in christian spaces. You and your peers should probably break off and form your own flavour, as the majority of christians will not back you in this matter, including the actual institutions who claim to teach the word of god. Your insistence is that the prevalent interpretation is wrong. Think about it. Even if that is true, if the wrong teaching is prevalently being taught in christianity, then it is still a fault of christianity.
