It’s not a problem until you make it one. There is as much chance of players leaving because they have a falling out with a BFF than if a relationship fails. Whether a player is gay should have zero impact on if that coach offers the player a spot on the team. And if it does that’s a coach I wouldn’t want my kid playing for
No one suggested discrimination or keeping gay kids off a team. I’m mostly wondering about policies and rules, and if that’s something coaches ought to consider. I've always considered team sports a place where kids could get away from romance and romantic expectations/pressure. Kids today have different views on sexuality and gender ID, and it makes the dynamics of things like sports teams different than it used to be.
And I think it’s wrong to think that a romantic breakup is no worse than a BFF one or an argument over a boy. Teenage romances, no matter the gender, can be devastating, and force a team into choosing sides.
