The political and legal movement to criminalise abortion in the US is on the brink of its biggest victory in 50 years. Most at risk are those who are already among the most vulnerable in our country – black and brown women and LGBTQ people who will be denied access to potentially lifesaving health care.

On December 1, the US Supreme Court heard arguments in the case of a Mississippi abortion ban. That law was written by a right-wing legal group. It was part of a long-term strategy to get the Supreme Court to overturn Roe v Wade, the 1973 ruling that recognised that pregnant people have a constitutional right to make decisions about whether to terminate a pregnancy.

Groups that want to eliminate access to abortion like to describe themselves using terms such as pro-life and pro-family, but those are deceptive. If we eliminate access to family planning and abortion services, the health of millions will be compromised. Some will die needlessly, and their families and communities will suffer. The same groups characterise themselves as pro-freedom, but they are aggressively trying to restrict people’s freedom to make decisions about their own health and families.

If you want a sense of how much parents’ and children’s health and well-being mean to backers of the abortion ban, take a look at Mississippi. When the state’s previous governor signed the ban, he declared that he wanted to make Mississippi “the safest place in America for an unborn child”. The current governor has used similar language, saying he made a commitment to God and to voters that he would do everything in his power to make Mississippi the safest place for an unborn child.

But what kind of commitments have these politicians made to children and their parents? When the Mississippi law was signed, the state ranked 50th in the health of women, 50th in the health of children, and 50th in the health of infants. It was the worst state for infant mortality. Things haven’t changed much since then.

Mississippi is also the state where black people make up the biggest percentage of the population. During oral arguments at the Supreme Court, the attorney for the health clinic that challenged the law talked about a deadly reality. She noted that “it’s 75 times more dangerous to give birth in Mississippi than it is to have a pre-viability abortion. And those risks are disproportionately threatening the lives of women of colour”. This is about political power and the corruption of our courts.

When Donald Trump ran for president, he promised conservative white evangelical leaders that he would put judges on the Supreme Court who would overturn Roe v Wade.

Don’t ever forget that Senate Republicans refused to even consider President Barack Obama’s last Supreme Court nomination for a year. They abused their power to create a Supreme Court vacancy for Trump to fill. Then these same shameless politicians took advantage of Justice Ruth Bader Ginsburg’s death to rush Trump’s final nominee onto the court a few days before the 2020 election as voters were already casting ballots to dump Trump out of the White House.

And don’t ever forget that the judges who are willing to sacrifice reproductive freedom are usually just as eager to allow states to restrict voting rights. The right-wing judges who vote to eliminate the individual’s right to privacy and health care are often the same judges creating new ‘rights’ to protect corporations’ ability to buy elections, get away with harming workers and communities, and discriminate against some of their employees.

Like the right-wing campaign to restrict voting, the campaign to eliminate access to safe and legal abortion has built power through organising at the state and national levels.

We who believe in freedom must do the same. Among the activists and protesters who gathered outside the Supreme Court on December 1 was a group of interfaith leaders who provided the moral clarity and urgency that the progressive movement needs to more effectively defend our freedom and our families.
