I hear ya, Andrew.
It's a weird dynamic in a way, that there can be something you love for years, then one bad moment will leave a permanent scar and it's never the same again. Because of that, nothing remains unsullied for very long because it's hard to never have any sort of bad moment of some kind. It does suck to have that nagging doubt that something crappy is hiding behind the curtain, but that's not on you. Don't feel guilty for enjoying something. The Blackhawks tragedy was horrible, but that's such an extreme case that it's not likely out there again, and so it's ok to sincerely like the NHL and a team (like the Avalanche for instance!
) or a band or a game series or a person/relationship or whatever, as long as there aren't known reasons not to. Enjoy the things you do while they last.
