I am personally acquainted with this person, as are my parents. That’s how I found this.
Most of the letter is of interest chiefly to Libertarians, but one part of it struck me as worth repeating:
On the topic of the Constitutionality of abortion rights, I could cite a right to privacy, which I do believe in, as a Libertarian. I think the government needs to stay out of our homes, our bedrooms, and our doctor’s visits. Yet, you support government violating the most sacred of trusts, the most intimate of issues. One that should remain between a woman, her doctor, her partner and her conscience.
If privacy isn’t enough, the Constitution contains a second support of a woman’s right to choose. You see, the thirteenth amendment of our great Constitution is the amendment against slavery. In 1865 our Congress ratified an amendment that said that “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.”
If a woman has not consented to sex, the possible result of that rape is, simply put, enslavement. However, a woman who consents to sex yet not to pregnancy, is still enslaved as long as she is involuntary bound to harbouring the body and developing life of something she did not consent to creating in the first place.
Her other objections are well-put and also may be of interest to more Left-leaning readers. You can read the full letter here.
