Accepting and liking are not the same thing. Mature, intelligent people understand they have to accept things happening that they don’t like about things they have absolutely no control over. Please explain how a fan of a team, someone who has absolutely zero control over anything regarding the team would go about “not accepting” a losing season.
The only real option to do so is to give up on the team and pick a new one, because the only relationship to the team is rooting for it, so the only way not “not accept” something is to stop.
