I don't think that the drugs angle which mainstream media chooses to approach bitcoin is that bad. Haters gonna hate. Lovers gonna love. Most drugs should be legalized anyway.
The problem there, regardless of your opinion on drugs, is that they have attached bitcoin to a completely different debate. This act in the very least is committing a logical fallacy and at the worst is predisposing people to dislike or like bitcoin because of their stance on a separate issue. It also potentially creates a self-fulfilling fallacy in that, if bitcoin is introduced to people as a currency for drugs and illegal activities, then only people interested in those niche activities will start using bitcoins.
This is dangerous territory because bitcoin is a currency, and thus could be attached to practically any cause, any thing, or any idea. Attaching bitcoin to drugs, especially when you are introducing them to people, is about as ludicrous as saying that dollar bills are inherently bad because I make it rain in strip clubs or because every spree murderer in the past 20 years has been "known to hold dollar bills in his wallet."
I can play that game too. For example, Hitler used paper money. Do you like Hitler? Most every hired killer has been paid in dollars. The currency of choice for engaging in the sexual trafficking of minors is, gasp, US dollars! Personally, every time I have ever committed a sin or done something morally questionable, I'm pretty sure that dollars were involved. In fact, I have dollars in my wallet right now and I plan on spending them on booze, hookers, and reefer, just to prove a point.
And I'm only going to use my bitcoins to buy Bibles and make charitable donations.
Okay I'm lying. I'm going to spend both currencies on booze, hookers, and reefer.
