After the fatal shooting of right-wing influencer Charlie Kirk, U.S. Republicans have a warning for Americans: Mourn him respectfully or suffer the consequences. Over the past several days, Democratic and Republican leaders have widely condemned the murder of Kirk, a 31-year-old activist and Trump world celebrity known for his hard-right views and pugnacious debating style.

A smattering of commentators — including ordinary people joking about and sometimes celebrating Kirk's death to lawmakers and pundits dwelling on his history of bigoted rhetoric — has also surfaced, only to be targeted in organized campaigns. At least 15 people have been fired or suspended from their jobs after discussing the killing online, according to a tally based on interviews, public statements and local press reports. The total includes journalists, academic workers and teachers.

On Friday, a junior Nasdaq employee was fired over her posts related to Kirk. Others have been subjected to torrents of online abuse or seen their offices flooded with calls demanding they be fired, part of a surge in right-wing rage that has followed the killing.
