Irrelevant and pedantic point here, but I would suggest it's more like telling someone they need to not have an ice cube in their scotch, very few scotch snobs would argue pro-ice :)
Just a transparent way of telling me you know how to drink Scotch. Damn knowledge snobs!
Actually despite being a scotch snob who spends a lot of his money on really nice bottles... I do enjoy it chilled sometimes (though a friend got me "whiskey stones" for Christmas, so I use them instead of ice!) I'm a snob to what I consider bad whiskey, not to what might be considered a bad whiskey drinker :)
