The "complaint" seems to be that it's "fetish material" that is "shoved into my face", by being the banner. I have news for people whining in that way: This world is full of a variety of things that have the potential to be a turn-on for a variety of people. There are folks outside the fandumb who consider furry, in general, to be a fetish. By that definition, practically every banner that's been on this site and everything in your gallery is "fetish material".
Granted, that angle on the argument takes it to the extreme and all the way to the fringe, but it's still valid. Looking at the banner in question, there's nothing even suggestive about it. It's two characters, albeit morbidly obese, but not even suggesting anything sexual. There are no "naughty bits" showing. They're not in a loving embrace. They're just fat on turkey day; the day when most of the USA over-eats and will feel bloated by the end of the day.
Furry is a fantasy world, where cartoon physics sometimes apply. If a cartoon over-eats, they're instantly fattened as an illustrative metaphor. As an artist, I'd expect you to understand that concept.
Forget about what the artist normally draws. Take the image at face value. If you didn't know that there were people somewhere in the world that would get their jollies on by seeing grotesquely overweight character drawings, what is the message that you'd get by viewing that image? What message would you get when you view these mainstream, Sunday newspaper comics?
They're cartoons. They ate a lot. They're fat. It's elementary, my dear Watson. Take a step back, take a deep breath, and realize that it's pretty silly to be offended by a fat cartoon.
