Ok, what is the distortion? You don't believe aborting an embryo is murder?
I don't know what you mean. The distortion is to says that Judaism allows abortion, and to use the catchphrase "life doesn't start at conceiving" to support it.
As for others not believing it's "murder", define murder. Its a technicality. It is strictly prohibited. The technicalities play a role in deciding excruciating circumstances.
