This is a bad comparison to make. Very, very bad.
First off, the Holocaust was a real event that really happened and really killed over six million Jewish people, Roma people, gay people, and various other groups that didn't fit Hitler's racist ideal. Real, born people, with names, souls, personalities, goals, hopes and dreams. Can we all please agree that their loss should be respected and not used for various political purposes and to demonize whatever we disagree with?
Second off, Godwin's law. But I'll keep arguing since I know someone who makes such a comparison won't respect that rule.
Third off, Nazi's were anti-choice. They used abortion to keep the numbers down of the groups they wanted to eradicate, and forced abortions onto those women. They did not allow abortion as an option for white women. Which means that the Nazi's stance on abortion was NOTHING LIKE the current political stance on abortion. Forcing a woman to get an abortion is a crime, and OB/Gyn's that perform abortions will refuse to perform one on a woman that says she doesn't want one. The choice is the most important aspect, because the choice was what the Nazis denied to the woman they forced to have abortions or denied access to abortions.
Fourth, showing pictures of Holocaust victims for any reason other then teaching about the Holocaust or remembering those who died and suffered during the Holocaust is WRONG. How dare anyone use these pictures for a shock picture, for a way to demonize their opponents?
Why am I talking about this? Because Brock Students for Life are hosting Stephanie Gray from the Canadian Centre for Bio-Ethical Reform to make a presentation comparing legal abortion to the Holocaust. And this outrages me.
