Junior Flemmings Incident
Despite prior praise over his support of the LGBT+ community,[50] McCarthy was criticized in 2020 by Outsports writer, Alex Reimer, over his reaction to a homophobia controversy involving the Phoenix Rising FC, where the San Diego Loyal walked off the field in protest and forfeited a match after midfielderJunior Flemmings was accused of using a Jamaican homophobic slur against openly gay Loyal midfielder Collin Martin, which was not heard by the referee or any other player.[51][52][53]
McCarthy was accused of questioning the veracity of accusations made against Flemmings, suggesting in a direct message with another Twitter user that the Loyal, who forfeited a match against the Los Angeles Galaxy II in the days prior over the alleged use of a racial slur against a Black Loyal player,[54][53] wanted to forfeit the match to begin with to continue making a statement on social justice.[53]
