It's not overblown all across America where the omicron wave did once again force ICU to capacity and cause the cancellation of non-emergency care across the country.
Herd immunity by vaccination is the only way to protect society without requiring infection, which fills hospitals and leads to deaths. Vaccination means you're about 40x less likely to be hospitalized or die, which saves our health system. Do you honestly believe there should be more discussion of infection immunity as a solution, when it results in 40X more hospitalization and death? I've seen anti-vaxxers call public health officials "genociders" for decisions far less death-causing than that.
If you think the vaccine mandate is why this convoy happened, instead of conservative fake news creating vast conspiracy theories from the "NWO" to "Q-ANON", funded by conservatives billionaires and the governments of multiple countries, to help destabilize and bring down the west, then to each their own. But how many Americans are among them? How many fans do they have abroad? It's not about Canadian mandates, it's about the global right wing conspiracy movement.
But I do not believe that the vaccine anti-mandate stuff is anything more than todays convenient whip for the very powerful forces of conservative media control to use to continue their war after Trump lost. Just another issue politicized for convenience, as until conservative media flipped the switch, vaccine hesitancy was almost entirely left-wing. Even in America anti-vaccination attitudes on the right did not start until post-election and post-vaccine rollout, and there's a large group of vaccinated conservatives who regret it because now it's seen as a mistake in that ideology.
