I don't think this will work. Excuse my nonsense logic but the swastika works well as a symbol of hate (despite having other origins and meanings) in that it has a single center with coherent angular spirals, the center signifying the ego and the spirals signifying logic and order complying with it... or something.

The hashtag has an empty center and four equal points that sort of radiate in multiple directions... seems more oligopolistic and ambivalent than totalitarian and opinionated.
