It wasn't a vicious sentiment, like you would have nowadays, just a feeling of superiority from adventure gamers. They also reacted fiercely when game designers started introducing action gameplay in adventure games, creating action/adventure hybrids. The feeling was that they were "dumbing down" adventure games. Which, if you read the Old Man Murray article, is of course a hilarious notion.
I loved adventure games too! As I said, I cut my teeth with the original (and punishing) Space Quest series, and to this day I have fond memories of it. I also learned quite a bit of English from the series :)
