We missed the original incarnation of PDD&D on tumblr, but you can read about the inception and evolution of this funny and feminist meme, along with some other Funny Feminist content, at the colorlines blog: http://colorlines.com/archives/2010/11/social_justice_comedy.html
The PDD&D was created by Diana Lopez, connect with her tumblr here: http://tumblr.diana.nu/
Have a look at the PDD&D and it’s multitudinous spawn here: http://www.memegenerator.net/Privilege-Denying-Dude
And here’s the fellow that volunteered use of his smuggest photo as the new face of PDD.
And another thanks to Beefy Betty for the tip!
