If you think this is subtle and nuanced, i shudder to think what you consider crass and unsubtle.
It was apparently too subtle and nuanced for RPGnet
From:
"This isn't "like playing a game about WW2 as the Nazis." This is like playing a game about WW2 where the Aryans get superiority bonuses."(Seemingly not understanding that the person with the least privilege wins the game...)
To:
"Hey now, let's not forget the third-party d20 supplement that treated women who gamed as mysterious, unknowable and all-controlling creatures that are not like us, the gamers."(Seemingly not understanding that this was the whole point of the Slayer's Guide to Female Gamers, to exaggerate to the level of absurdity the - presumed - male attitude towards women in the hobby).
Or:
Chav the knifing is classist.(Seemingly not understanding that the real target was tabloids like the Daily Mail and how they create a demonic image of the underclass. Were I doing it today the target would probably be UKIP and the BNP via immigration with a side-swipe at White Wolf's notorious Gypsy supplement).
Then there's the weird attitude that the cards from this game somehow represent my own views. Take the 'brown person' card, which simultaneously makes fun of peoples (presumed) inability to tell certain races apart AND the tendency of some to use this inability in others as a bludgeon during argument. Similarly, other card 'quotes' are there to make fun of people's backward attitudes. The transwoman one - for example - talks about 'concealed carry' now being legal in many states.
I keep coming back to the Suey Park/Colbert thing as its recent enough for people to remember and it carries across pretty well. If you've seen her HuffPo interview you'll note that she doesn't really seem to understand how satire works and then descends into self-parody at the end.
Perhaps if my name hadn't been attached they wouldn't have read it according to their existing prejudices. We'll never know.
It's funny how the old lies rise to the top again though and no amount of refutations seem to gain traction.
