Just a small suggestion: I think The Chapter of Brotherly Flesh has a nicer ring to it. I don't mean any offense, of course, but "Brotherly Fash" sounds kind of kitsch to me. Also, Brotherly Fascism is a perfectly fine message, but there's something more visceral about Brotherly Flesh, as if to say that we're bound not only by fascistic ideals, but by flesh and bone, i.e. race.
Moreover, the names of these groups definitely shouldn't be taken lightly; a lot is gleaned from a name. We shouldn't act like LARP faggots fussing over our pronouns, but some quick aesthetic mind in the design of these names could make our cause that much more appealing to the uninitiated.
