I’m not judging anyone, I’m putting a warning out there, because most will experience far worse than this.
I supported this team for 18 years as a sth, missing maybe a dozen games. This game, this team was what my son and I did for nearly two decades together, that same son died at 24.
Please note that I also warned that ownership were asshats. This end result should come as no surprise to anyone.
My dad died when I was 23 and hockey was the main thing we talked about and watched too. Not from Arizona so wasn't our local team but if we were it would have been. Our local team was mainly what we talked about over the years.
Everyone grieves differently. Everyone feels differently. If you don't understand why someone is upset than don't act like it's a problem that they are. People will go through worse than this...maybe! But even if/when they do that doesn't invalidate how they felt about this.
People are wired differently and what matters to you might not matter to someone else and vice versa. We all have different situations and it's never the exact same. My cat died nearly a year ago and that loss was on par with my Dad's despite me having my cat for only 12 years. For others, death of a pet would mean nothing. None of those are the wrong way to feel. There is no right way to feel.
There's no point in comparing suffering and "warning" people to toughen up. There's no wrong or right way to cope with things. And there's no wrong way to feel. Whether people feel more strongly about loss of an NHL team, or death of a loved one, or losing their job, or whatever, it has nothing to do with you. Don't blame the fans for feeling the way they do or for "not supporting the team enough" and don't be a dick to people grieving the team when you apparently don't understand why they would even be doing that.
Your own feelings about how the writing was on the wall, the fans never cared about the team, and that the hockey team moving is no big deal are all perfectly valid personal feelings too. I'm not gonna shit on you for having those. But you don't get to shit on other people for having a different opinion or for coping worse than you are.
