No, feminism does not allow man shaming. I do realized there is plenty of man shaming still happening in this world today, but I don’t think it’s all because of feminism or that it’s all being done by feminists. Feminism seeks to allow women the same political, social and economic freedoms as men.
Feminists don’t want to shame, disgrace or dishonor men in any way. In order to achieve equality, feminism teaches women to be kind and respectful to others, regardless of their gender, political leanings, social standing, and economic background. If you see man shaming happening, you should speak up against it.
