Lots of reasons! It took years to finally accept the reality of abortion and fight against it. But here’s a few things that really did it for me:
1. Tumblr blogs – specifically Cultureshift. I love his/her blog! Seeing responses to questions or comments from pro-choicers that I myself frequently would ask (when I was pro-choice) were so on point, logical, and deep down I knew he/she was right.
2. Watching two of my friends suffer after their abortions. It was heartbreaking. They went from loving life and being happy to depressed and suicidal.
I think those two reasons are what really helped me make the switch. Information and personal experience, the recipe for taking an adamant pro-choicer and making her pro-life.
