I don't know, someone reducing him to just a junkie, probably never gave his music a chance or then did, but didn't like it. I find it weird if someone finds the time to go to forums and just criticize someone they claim not to care about. Especially as Scott wasn't in the news all time, so that everyone and their mom had an opinion.
In a way I get it, take someone like J Bieber, few years ago everyone seemed to go "oh that annoying, spoiled brat", and if you said that, chances are you didn't care for his music and only saw some annoying kid. Now if you matured a bit, you can see the guy has talent, has not had the easiest life as a teen pop star and you understand most people screw up a lot and fame makes you a little crazy. You can accept someone liking an artist or the art even if it's not for you. Okay a bit off the rails here, but anyway.
For what it's worth, I do draw the line somewhere, what I "allow" my heroes to do, but drug use isn't enough. Of course that doesn't mean that I praise someone for it, I like them in spite of it.
Loved his persona, most of his music and when sober he came off as a really great guy in interviews. Felt and still feel a spiritual connection to him, and it was just unfortunate he could't kick the poisons and get his act together. But that whole, "how can you like someone who's such a junkie" mentality I don't get and is so hypocritical, I mean take almost anyone, let them name their top 10 artists and there will very likely be a few people with similar issues.
And in general there are celebs who have done far, far worse things than SW who are praised as Jesus by everyone and their granddad.
