What are you talking about? Furries aren't always fat, if you think that then either you like them REALLY skinny or you're looking at the wrong galleries.
Eh. For some creatures anything that doesn't look like it just crawled out of Auschwitz after ten years of imprisonment is considered to be "fat". Whatever that means in their demented little nerve ganglions.
Just like that fucker that complained about all Western artists being obsessively in love with filth - excrements, piss, vomit, and such. Unlike all the non-Western artists populating related tags on this very site.
When Asprin poked fun at Americans in one of his Myth, Inc manuscripts, he depicted a society composed of exactly two kinds of people - shapless blobs of fat, and emaciated sceleton-like creatures. Guess he had a point, and we've witnessed an encounter with the second kind here, during its favourite activity - pointless complaining, as they usually do.
Was gonna post a quote from Leiber in place of this wall of text, on the inherently disgusting nature of anything covering the bare bones - including flesh, naturally - but I can't remember where exactly have I read it, and could not be bothered to dig through my library to find out. So here's my TED talk instead. Thank you for coming.
