If I could only recommend one pro-life site it would definitely be Abort73.com. They have thorough, accurate, eye-catching, easy to follow layouts and content.
I use their medical testimony page often, especially when encountering those who claim that we don’t know when life begins. They list quotes from many mainstream embryology textbooks pointing out that a new human being is created at conception.
Please check out the site if you haven’t already, then bookmark it and share it!
