Welcome to international sports fandom. It's nasty, ugly, and etc., but it's the reality athletes chose.
Now if Ellis and Rapinoe did an exhibition match at BJU or Liberty University, which they probably detest, would they truly expect anything like this kind of crudity from Bob Jones or Liberty students and/or faculty? The greatest "danger" they'd face would be the delicious donuts and other foods they'd be offered by those schools' hospitality! And maybe the "danger" posed to their stereotypes by meeting real Evangelical and Fundamentalist Christians.
