Like many places, USA TODAY values “equality and inclusion,” but only as long as it knows its rightful place, which is subservient to white authority.
You were probably right to assume the killer was white and male since there are more of us in the US. And yes there are plenty of examples of white male mass killers. Never heard of a female mass shooter by the way.
News organizations have one major requirement that they report the news accurately. Sure some news outlets follow a conservative or progressive agenda and select facts to support their side. But news organizations who make up their own facts lose their reputation and lose their subscribers or viewers because of it.
Your position as "race and inclusion editor" required you to tell the truth about race. There was room for nuance but it had to be based on fact. You made a statement that was untrue about the race of the killer. You just make another possibly career ending untrue statement about your employer. USA TODAY is not an organization that is "subservient to white authority" unless you can prove otherwise. USA TODAY has a reputation to protect as truth teller. They fired you because you made a public statement that was untrue.
Ms. Jhaveri I am sorry you lost your job. You are a bit of a celebrity right now so you may have new opportunities to write for other publications.
