Listen man...and this is so simple I can't believe anyone can't understand it.
You get the vax so you are protected...but the unvaxxed must be fired to protect the vaxxed who are already protected by the vax. The vaxxed can still get the virus and spread it to other vaxxed people, but it is the unvaxxed that are the issue because the vax is mandated. It is the mandate that somehow amplifies the danger from the unvaxxed to the vaxxed even though the vax protects them from the virus.
You got it? It actually makes perfectly logical sense...
