Why do we share information like this as if it is factual? What I mean is that each of us actually has to choose who the "authorities" are in our lives. ' "Canada" to require all ….' If you pull that apart a bit, there is apparently some amorphous entity called "Canada" that somehow magically can render this so: All travelers must be vaccinated. Do you think Trudeau will need to be "vaccinated"? Bill Gates? This is for the plebs only. How about crashing air travel for a hot minute?
I don't think ANYONE should take orders from entities unknown as man or woman to them. "Canada" can no more issue "decrees" than "toothbrush" or "dildo" can. If my manager at work (a job I voluntarily chose) requests some job appropriate action from me I may choose to comply due to my desire to continue to be satisfactorily employed or because I agree the action is warranted. I recognize the manager's role, but I am not slave to the instructions.
We need to ask who (man or woman) is responsible for the instructions and why we should consider they have authority over us.
