Not that I'm convinced of #1. Sometimes people needed to be slapped on the face with something like this before they say it. There are a lot of dirty old men in comics and fandom who need to see "hmm, this is kind of disturbing."
So is all satire in literature, film, television, etc. a waste?Like I said before, commenting on something, when you could be acting on it is a waste. It's passive.
No, this will be read by more people and be more commented on.I don't find it particularly praiseworthy. It's not like he's some indie comics creator who is dissatisfied with the state of the industry and trying to make a point from the outside with spoof or allegorical characters.
