I could be completely wrong on this but the impression I got from early FoLC discussions on this - meaning while the series was still on and those magic episodes were very fresh in everyone's minds
- people's reactions pro or con seem to stem from whether they perceive Superman to be pure fantasy or more science fiction. People who see him more as a fantasy creation don't seem to have as much problem with his magic vulnerability and, conversely, the more sci-fi they see him, the more they resist the idea.
And then there was that whole other camp that appeared to want nothing more than to have him be the ONLY thing in the L&C universe that had powers period. Those individuals tended to object to magic in and of itself.
Like I said, I could be completely misremembering this but I don't think so. I got into too many discussions on the topic.
