Generally agree, but I do have to bristle with the "huge losers" sentiment. The fact that furries/weebs have a strong visibility in the professional software/IT space should be a signal that those people aren't losers, and are in fact doing quite well for themselves. And if you're in the industry, then you need to do yourself a favor and remove that label from yourself.
What you call a "flagrantly display", I call a typical, progressive break from meaningless social conventions. People like cute drawings and post them on their websites, so what? And I think it provides good visibility to those communities to demonstrate the skilled and creative people that inhabit it.
