Erm, after realizing that I myself didn't read the original post clearly, I have only this to say.
A Fascist faction? might be interesting, yes, and could possibly create some very nice Roleplay.
HOWEVER
If you wish to create a fascist faction purely to get away with creating something along the lines of a large scale Xeno Movement, i.e. (So you can get away with being basically a Nazi) by saying "Oh no we're fascists, not Nazis" Well then, that is incredibly a bad idea.
I guess I should've read more carefully.

I was gonna correct myself yanno...but uhm, I love you too. XD
