Thing is, in the 1920s and 1930s fascism did not carry a strong negative connotation. Mussolini's regime was mostly viewed in a positive light by democracies until the invasion of Ethiopia and adoption of racial laws. This was social context when Brave New World was written (note the "Benito Hoover" character).
I'd suggest reading these pieces:
1) "UR-fascism" by Umberto Eco http://www.themodernword.com/eco/eco_blackshirt.html -- attempts to define salient features of fascism across the different regimes.
2) "Three New Deals", http://www.amazon.com/Three-New-Deals-Reflections-Roosevelts... -- title speaks for itself
