A Michigan father says his family received alleged death threats, racist abuse and a bomb threat after his teenage daughter publicly discussed competing against a transgender volleyball player without initially knowing the player was biologically male. The case highlights the intense personal backlash surrounding disputes over transgender participation in girls’ sport.

The daughter, Briley Lechner, is 16 and said she faced a transgender athlete in a girls’ volleyball match before later speaking out in support of women’s sports. Her father said the family then endured harassment online and threats of violence, though the article does not establish whether any threat was carried out or identify those responsible.
