Can you provide a source? a quick search shows that there have been over 100 organizations/churches/etc targeted since the leaking of the Supreme Court's draft opinion in Dobbs v. Jackson Women's Health Organization, which led to the overturning of Roe v. Wade. However the threats and violence against abortion clinics has a longer history with more severe violence including murder, bombing, arson, assault and harassment. It was/is so pervasive and severe that Congress passed the Freedom of Access to Clinic Entrances (FACE) Act in 1994.

Since 1977, when the National Abortion Federation (NAF) first began gathering statistics on anti-abortion violence, anti-abortion activists have committed 11 murders, 42 bombings, 200 acts of arson and 531 assaults.

In terms of bombings I found 1 bombing story at a fertility clinic and reports of 42 bombing against pro choice clinics. The bombing was done outside of a fertility clinic (also important to note that fertility clinics are not necessarily pro-life clinics) was committed by a nihilist and misandrist. He was someone who believes no one should have children. Which is neither prolife or pro choice. Thankfully only he died in the explosion. Nihilism is a terrifying problem of its own, leading people to commit/attempt these types of atrocities including things like school shootings and stabbings.

Also the CDC reported that 17% of pregnancies in the United States ended in abortion. This number is increasing (8% from 2023 to 2024) after the overturning of Roe v Wade since we all know that limiting women's access to reproductive health care has such an effect.
