Punk rock singer Courtney Love, the widow of Kurt Cobain, went after Leftist Muslim activist Linda Sarsour on Twitter Wednesday morning over Sarsour reportedly raising money off a nonexistent hate crime, writing, “You’re a vile disgrace to women and all mankind @lsarsour”.

Sarsour responded to Love and the two engaged in a vigorous back and forth with Love bluntly calling Sarsour an “anti-American fear mongering fraud” and of “inciting hatred towards Americans.”

You're a vile disgrace to women and all mankind @lsarsour — Courtney Love Cobain (@Courtney) June 7, 2017

Love also held her ground against defenders of Sarsour before Sarsour joined the discussion.

not when she's using fake stories to generate sympathy and collect $$ under the mask of women's rights and solidarity. that's just wrong! — Courtney Love Cobain (@Courtney) June 7, 2017

I worked my ass off my entire life to defend women, I didn't create fake stories and lie about them nor rip people off financially. Linda 👎 — Courtney Love Cobain (@Courtney) June 7, 2017

yea, seems like a publicity stint and perhaps it's been effective for her, but I know a rat when I see one — Courtney Love Cobain (@Courtney) June 7, 2017

I feel there's zero sincerity in her actions you claim. https://t.co/JTvB29FxTP — Courtney Love Cobain (@Courtney) June 7, 2017

Sarsour and Love then engaged in a back and forth with Love calling Sarsour an “anti American fear mongering fraud” and Sarsour calling Love “anti-Muslim”

So Courtney posts a right wing article to make no point. https://t.co/upEwgLneX6 — Linda Sarsour (@lsarsour) June 7, 2017

Don't blame the right. Blame that you did zero research on this fake story but you rushed to take everyone's money. #youareafraud — Courtney Love Cobain (@Courtney) June 7, 2017

Police report doesn't deny that Rahma was brutally beaten as someone who intervened. Where are all witness accounts? Using couples story — Linda Sarsour (@lsarsour) June 7, 2017

that's an official release, you're continuing to refute it. Just accept you were wrong and you jumped the gun. Goodbye lady! — Courtney Love Cobain (@Courtney) June 7, 2017

Would you also support the Columbus OH Police Department who still hasn't fired an officer who kicked a handcuffed Black man on video? — Linda Sarsour (@lsarsour) June 7, 2017

Don't drag in another race related incident or possible on going problem to support the fact you're just inciting anti American rhetoric — Courtney Love Cobain (@Courtney) June 7, 2017

Well now I believe she's nothing less than a fraud.. she appears to be a anti American fear mongering fraud. — Courtney Love Cobain (@Courtney) June 7, 2017

There's two different women. Rahma came later to scene. No one knows exactly what happened. That's the police's job to find out. — Linda Sarsour (@lsarsour) June 7, 2017

but you quickly called it a hate crime and collected thousands of dollars on a story the Columbus Police claimed has no credibility. #fraud — Courtney Love Cobain (@Courtney) June 7, 2017

Thanks @Courtney for clarifying what side u are on. Not the side of justice or u would be demanding accountability 4 brutal assault of Rahma — Linda Sarsour (@lsarsour) June 7, 2017

I'm sorry Linda but I feel you're a fraud and you're inciting anti American rhetoric. I have zero faith in you and your plight. very fishy — Courtney Love Cobain (@Courtney) June 7, 2017

Thanks @Courtney for clarifying what side u are on. Not the side of justice or u would be demanding accountability 4 brutal assault of Rahma — Linda Sarsour (@lsarsour) June 7, 2017

I'm on the side of all human equality rights,spreading knowledge and encouraging peace and understanding.I feel you have the opposite agenda — Courtney Love Cobain (@Courtney) June 7, 2017

Don't apologize for ur veiled anti-Muslim rhetoric. I will always fight for my country to be a better nation that respects all its citizens. — Linda Sarsour (@lsarsour) June 7, 2017

that's my point, I never mentioned any religion. you just confirmed to me you're an anti-semite anti American fraud. Goodbye,I'm done with u — Courtney Love Cobain (@Courtney) June 7, 2017

Reading is fundamental. We all said it was an "alleged hate crime" and we are STILL demanding a full investigation which still didn't happen — Linda Sarsour (@lsarsour) June 7, 2017

no, all of your posts yesterday asserted the alleged incident as fact and you immediately began collecting money and calling it a hate crime — Courtney Love Cobain (@Courtney) June 7, 2017

Dissent is the highest form of patriotism. I will keep speaking truth to power. You aren't the only one who won't like it. https://t.co/TfryJ0c5UI — Linda Sarsour (@lsarsour) June 7, 2017

No, you are lying. you are making us all look bad.what happened here is that you got caught stirring a pot of falsity. why? seems criminal — Courtney Love Cobain (@Courtney) June 7, 2017

I didn't even know nor care what religion she is. I was calling her out for exploiting a fake story, inciting hatred towards Americans — Courtney Love Cobain (@Courtney) June 7, 2017

Courtney Love. Wow.
