Goths have never been cool to anybody other than goths. Goths were basically a response to the homogeny of the people percieved as the "normals" - of course, that response was to become an instantly recognisable and completely homogenised group themselves, always entertained me that. I have no idea what Total Drama Island is, but I never saw Sid as a goth in the slightest.
Groups like that are something you tend to grow out of pretty quickly I think.
