I've never heard of him until reading this question.
Well he seems like a nice chap, doesn't he? (Sarcasm intended)
I'm actually interested now to have a look at his site and read his nonsense, but I have to agree with Jennifer, I wouldn't like to give him the satisfaction of adding to his web traffic.
He's maybe, at best, half serious about anything. His book is obviously satire (ie: meant to be taken literally by stupid people). He does lean conservative/ libertarian. An ongoing joke is that the Dick Masterson Twitter account only follows Donald Trump. I'm not going to divulge his real name. He jokes about being an alcoholic a lot... but has also mentioned being way too busy to drink for over a week... something no true alcoholic could probably pull off. Truly a man of contradictions.
His current podcast can be found at thedickshow.com, so judge for yourself (don't worry, it's funded by patrons... you aren't giving him ad traffic or anything). It's a spin-off from his previous podcast, where he apparently didn't get along with the other host (Maddox... an actual troll, now turned more of a social critic than anything else). Conversations between the two made it apparent that Dick actually treats women far better than Maddox.
