Conservative youth leader Zana Ramadani - whose family are Albanian-born Muslims - stripped naked and draped herself in the ISIS flag in the extreme protest.
And on her bare boobs she scrawled in block capitals 'F**k Your Islamism', as she is snapped giving two fingers to the terrorist group.
Ramadani, 31 - also a member of the breast-flashing women's rights protest group FEMEN.
The Junge Union leader of the CDU conservatives in Wilnsdorf, central Germany, said: "This flag offends many Muslim people.."
But Ramadani once infuriated Muslim leaders herself when she posed naked for a picture holding a banner which said: "Muslim Women Let's Get Naked."
And on her bare boobs she had daubed: "F**k Sharia".
