Yes, that's the way I looked at it as well. Having discriminating tastes (like in music) is not at all the same as being a snob. I always thought, part of being a snob is being offensive and/or disdainful. I wonder if across the pond, the word has a more positive connotation than it has here.
Just having discriminating tastes does not make you a snob. If you enjoy music, or food, or life in general, then you will be always curious to discover what other people like, to find new things and to share your passion by connecting with other people.
A snob does none of these things, because he really prefers to separate and distinguish himself from other people. The disdain for other people's tastes is inherent in the definition of the word snob. There has to be some value scale implied.
It doesn't matter whether it is a soccer hooligan making fun of a guy on his way to the opera, or whether it is a wine snob recoiling in disgust when a neighbor offers him a Pabst Blue Ribbon, the same emotions are at work.
If Milongadicto's blog was solely concerned with discerning his favorite tango music and favorite examples of tango and musicality, then it wouldn't be about a tango snob.
If you read his latest blog post it is even more clear that the unifying and dominant theme is his disdain for other people, and anger toward them. I need not supply any quotes; he is quite explicit.
The only thing that makes it of any interest to read and not just another venom filled rant is that he is perhaps just a tiny bit conflicted, and more than a little bit dissatisfied. He doesn't like being a snob. So he may learn something from the experience. I tend to like being a snob, so it is harder for me to see my fears and insecurities that underlie the gratification I get out of feeling superior to the teeming masses.
