I wonder if anyone notices.
Kelly comics are intentional satire of the political comic style and topics.
Kelly is one of the best parody comic creators in the business. I believe he works for The Onion?
The “Stan Kelly” persona itself is a fictional satire. The work is actually done by cartoonist Ward Sutton, whose standard political cartoons under his own name criticize the right wing directly.
It’s more like the Colbert Report back in the day, an exaggerated right winger who is so obviously wrong it’s funny.
The character “Kelly” isn’t explicitly right wing, instead he’s supposed to be as wrong as possible. As an example rather than “Pro-choice” or “Pro-life” Kelly is “Pro-abortion”, because he hates children and thinks they should be aborted before they have a chance to destroy their parents lives. Or the comic where Kelly opposed drug legalization… because police dramas wouldn’t have anything write about.
Oddly, Kelly’s “wrong as possible” stance does seem to frequently align with right wing politics, for some reason.
