Obviously, lacking any other solid evidence to substantiate this claim, I have taken the position that it is total crap. Norman Spinrad faced similar accusations after the publication of The Iron Dream in spite of its obvious satirical nature and Spinrad's long stated Anarcho-Syndicalist political philosophy.
My bottom line belief is that a good author can write against type. Many do use their work for a philosophical "soap box" but not necessarily everything someone writes should be taken as a window into the deep, hidden recesses of their soul. Having attempted to write against type myself a few times, I have gained a good deal of respect for those who can do it well. I tend to get bogged down in disliking protagonist characters with whom I would normally disagree or even find reprehensible. I see where cardboard villains with bumbling subordinates and cannon fodder minions come from. It's hard NOT to write such characters as silly, maniacal, violent but wretched buffoons who ultimately destroy themselves with a bit of help from "our hero".
In part two of this little diatribe (dear God, a part two? NOOOOOO!), I'll discuss my own descent into madness while attempting to create a believable and maybe even somewhat likable "good bad guy" that has consumed a fair amount of my limited spare brain power over the last year or so. Stay tuned and keep some extra strength aspirin handy!
