The way I see it calling out a whole ethnic group (as opposed to the specific organization/group doing something "bad") is the issue. It would be like a politician telling all African-Americans they to work to stop an outbreak of gang violence or saying all Italian-Americans need to work to stop a Mafia War. Of course that would piss off members of an ethnic group/race/religion that aren't involved with whatever is being addressed, whether it be gang violence or congregating in large groups during a pandemic.
