"Well, guess what? I take my side. These streets are as much mine as they are of undeserving ones like you. You or a hundred like you will not scare me into staying home and not being free. This is a message from all the strong girls to you and your likes: if you try curtailing our freedom, we willfight back. And we will knock you down," she wrote in her post.
