Well, I don't see the similarity at all, and apparently you were already aware of how complete over the top it was when you posted it, so that's even worse. The analogies of skateboarding and grafitti - which someone brought up in a comment below - are far superior and much more accurate than this highly charged and way off-target example you decided to unveil to the world.

And you're right that a disclaimer wouldn't have helped. I just think that in this case, if you knew this analogy was inappropriate, you should have delayed posting until you came up with one that was less offensive and ridiculous.
