Athletes face prosecution and/or deportation.
In Russia it is now illegal to even speak about homosexuality around minors, much less openly display gay pride. Technically the ban is against "propaganda of nontraditional sexual relations" around minors, but the implication for openly gay individuals is clear. Public displays of affection by gays, including holding hands or displaying symbols like a rainbow flag, are now banned. Violators face steep fines and jail time; foreigners face similar penalties plus deportation.
