The best secular pro-life debate is going on now in my country - Canada - though the government refuses to open up the discussion.
We are the only country in the world that has NO laws restricting abortion. Whatsoever. For any reason, at any time, a woman can legally get an abortion. Right up to full term.
A study was done recently that noted that many of our immigrants are coming here, finding out through ultrasound that their child is a girl, and aborting it. They want a boy.
The idea of people killing
girl babies has set off a cry of outrage from the feminists and atheists. Apparently, female fetus’s are ‘women’, and they deserve life. (The males are ‘a clump of cells’ still, and deserve nothing

).
This new debate might make a good point to your article. A secular society that feels a woman has every right to completely control her own body even if it includes aborting her baby - yet has a problem when women use that right to murder future women!
So, is aborting a fetus for any reason, at any time, okay -* so long as it’s a boy*? Major holes in the arguement there I’m sure you could get something out of.
