Employers being reluctant to fire an employee because the employee is a member of a minority is pretty much a myth - particularly in jurisdictions such as the US where employees generally do not have much by way of job security. At best it will just make the employer double-check to make sure they have dotted the Is and crossed the Ts before pulling the trigger.

Also, forgive me, I don't know a universally inoffensive way to broach the subject, but people expressing a fear that minorities are receiving unjust benefits are often racist?

See what I did there?
