Perhaps it was the rather strong position this guy took on those who drink that spurred some of the drinkers to respond as they did. You're article seems very judgmental to me; it seems that "hip" kids or straightedge kids or whatever scene you might come from that does not value drinking in anyway are as judgmental and closed minded as many of the "drunken frat boys" so often referenced, even here.
To each his own, it takes all kinds to make the world go around and to assume that most people drink out of insecurity or boredom is not a very well thought out assumption. If I went around basing thoughts and opinions using anecdotal evidence from high school and college life would be rather ridiculous.
Good for you for not wanting to drink. Good for me for enjoying cold beer.
Have a good one.
