Lanikai,
The picture you requested removed is a well-known image macro that's pulled out every time an argument gets silly. I'm shocked you've not come across it before as it's been popular on most forums in the last 5 years.
Oh, and the text is "Arguing on the internet is like running in the Special Olympics ..." with a picture of a Downs kid winning a race. Yes, it's sick humour, but let's not become over-sensitive. Internet forums are like school playgrounds, we have sick jokes, bullies, cliques and over-protective minders; the humour usually regresses to school kid humour. Don't over-analyse it and don't over-react.
It was posted as an insult to my internet persona and as such was brushed off like all childish humour - in the manner it was intended.
Dude, it was just a crap joke.
