Well if someone sees zero value in a player, they see zero value in a player.
If they say “I hope Loui Eriksson never plays hockey again and dies a miserable death”, that’s hate. An all consuming emotion reaction that is laser focused on its subject.
Personally, I don’t know Eriksson, so I can’t hate him.
However, I do feel, having watched the majority of games last season, that he was a lackadaisical floater akin to an empty uniform on the ice. That’s not hating, merely an observation with negative connotations.
