f off with telling me what to do
But government tells you what to do all the time.
Governments.....um....govern.
The government tells you that you can't murder other people, it tells you that you can't sell rotten food to the public, it tells you you can't start fires on someone else's property (and it provides you with a fire department in case someone does it anyway)...
Protecting the health of its constituents is a legitimate function of government. You can't "pursue happiness" and enjoy liberty if you're dead or on a ventilator.
If there is a once-a-century pandemic that can potentially kill millions if ignored, and the government says "hey, you know, maybe not quite so many hundreds of thousands have to die if we mandate that you take this painless, mildly inconvenient step"....I'm OK with that.
Commence with the "slippery slope" arguments if you please, but that's the way I see it.
