You got way more flak for how you follow-up that first post than for the initial thought.
If you would have left it at the first post there would have been very little reaction I think.
Posters were happy to see him smiling again on the ice, seeing what had happened just a couple of months before that. As I said your first post on it was not a big deal, but going on it became more about other issues rather than the issue you began with (Larsson supposedly injured, going after any poster even mentioning that he could have offense, etc).
Just to be clear, Larsson seemed to be smiling in 16/17, and to me it looks as if he is smiling now (at least I hope so). Tragedy as I said affect people differently, and I think you acknowledged this back then as well. I know OEL talked about the passing away of his mother which had his head spinning even the full season after it happened and that often he felt that he couldn't even go on the ice (of course he did anyway, but it was a bad year for him). Others have probably handled it much better.
It is a touchy subject though so I don't think it is at all surprising to see strong reactions about it.
As I said, I like how he looks and sounds right now and I hope he will come in and have a good year. Also liked Tippet's comments (which to me mean something very different than to you).
We definitely need him to find his game again.
