You ask for a case. I show you a case. You say “good for them”. So you agree they are requiring vaccination proof or “passports” to travel in Canada. That is where we differ and I do not say “good for them”. The requirements of vaccination and masks against COVID has nowhere near the same proven benefits and need as measles or smallpox vaccinations do. This is a typical tactic of those protecting a weak position...bring out the extreme cases to support a radical view.
