Judging by some of the reactions I saw on social media, David did have some detractors. That's fine. We're not all perfect.
But this is just the Internet. Not everything needs to be taken personally.
When a prominent member of the fan community passes- and I think David Downs certainly qualifies- it's a significant loss. Because that's, at least in my book, one less person who gets why we're fans. And that sucks. (So does going as young as he did, but I think you understand what I'm getting at.)
I hope that, however he went, it was painless and easy, and also that his family finds solace, strength, and peace through all this.
