Members of a women’s fishing team refuse to compete alongside trans teammate

Why is there an issue with 'trans' but not 'women's'? If they're going to divide up (exclude) sexes, perhaps make a 'trans' competition too.
Seriously. Do they think men have an advantage over women because it's normal for a dad to take his son fishing growing up? I really can't think of any other reason.
Women's sport is not necessarily about having a physical advantage. It can be the case that the sport is simply male dominated and then, especially when there's no physical reason, women may feel like it should be advertised to girls more. And that's what then leads them to organize women-only championships.
