I mean, it is because you can look for another job or start your own business if that's the hill you want to die on.
But in general society has rules and we must abide by them if we want to participate. For instance I'm sure most people wouldn't appreciate if I walked around naked, which does not harm anyone unlike needlessly having an increased risk of contracting and/or spreading COVID.
Please stop spreading misinformation. I encourage everyone eligible to get vaccinated, but by your definition vaccinated people are also "walking bioweapons". The main benefit of vaccination is in preventing severe symptoms, not transmission. Since the virus is now endemic we'll all likely get infected eventually regardless of vaccination rates.
Can we please just stop? “Take this or lose your job and pension” is not a choice.
