Sara Fernanda Giromin, a radical feminist who founded the topless female activist organisation Femen Brazil in 2012, has completely transformed into a pro-life advocate and asked Christians for forgiveness.

Giromin, also known as Sara Winter, now criticises the feminist movement that she once headed, calling it a "completely toxic environment, filled with gossip, intrigue, humiliation and persecution," according to News.com.au.

Giromin now opposes feminism and abortion, saying it "promotes the destruction of the traditional family and all moral values ​​of society."

Her sudden change came after the birth of her second child last October.

In a YouTube video she posted last Dec. 15 titled "I ask Christians for forgiveness for feminist protest," Giromin offered a heartfelt apology.

"Asking for forgiveness is certainly not an easy thing to do. We went way too far and ended up offending many religious and non-religious people. I feel extremely happy and welcome. I never imagined that religious people take 'forgiveness' seriously. This is a learning experience for all who criticise Christians," she said.

She added, "I thank all the Christians who have supported me and given me space to spread my new visions. God bless. I ask Christians for forgiveness."

In her book, "Bitch, No! Seven Times I Was Betrayed by Feminism," she wrote the abuse she experienced at the hands of other feminists.

She said she was pressured by fellow feminists to take drugs and have sex with strangers.

"Lesbian and bisexual women have much more voice and respect within the movement, so in the search for recognition of my struggle, with each day that passed, I deconstructed my heterosexuality and was substituting it with an artificial bisexuality," she said.

Giromin aborted her first child but changed her stance when she gave birth to her second child.

"I have repented of having had an abortion and today I ask for forgiveness," she wrote, according to Life Site News.

"Yesterday marked one month after the birth of my baby and my life has taken on a new meaning. I'm writing this while he sleeps serenely on my lap. It is the greatest sensation in the world. Please, women who are desperate to abort, think carefully about it. I was very sorry I did it. I don't want the same for you," she said.

After leaving Femen in 2013, she joined Bastardxs, a feminist group with men and women as members. But now, she abhors feminism in all forms.

As time progressed, so did her attitude, and she eventually rejected her bisexual status.

"For the feminist sect, women are not the inspiration, they are prime matter in the worst sense of the term. They are convenient objects useful for the purpose of inflaming hatred against the Christian religion, hatred against men, hatred against the beauty of women, hatred against the equilibrium of families. That's what feminism is, and I can guarantee it is like that because I was on the inside!" she said.
