Sean was some completely disgusting junkie loser, which is exactly what OP did. They even used the word "junkie."

You're putting words in OP's mouth. Sounds like you've got a chip on your shoulder for criticizing about addiction, since you're recovering as well

OP isn't breaking new ground here. OP called Sean a junkie not a disgusting loser. Sean is a heroin junkie just like Fiona is a chaos junkie and Lip is an alcoholic. Isn't all that established in the show itself? In S07E01, even Frank says

That fcking junkie Sean

So what do you have to say about that?

I'm pretty sure most of the comments here, in this very post, are pro-Sean

Pretty sure huh? I admit Sean isn't the worst but There's an entire thread posted about Fiona's ideal match two days back. It was trending too. Not even the bare minimum mentioned Sean. Surprisingly even Gus got mentioned
