Someone once asked me that question, and I had the fun opportunity to let them know that my mom did in fact get several abortions before me, which is what allowed her to get to a better place in her life before having me and my sister, giving us a better life than if she'd had a kid in her teens.
Plus, if that first pregnancy had come to term, she never would've had me and my sister, so ehy does the first pregnancy get more right to live than the potential second?
