The US is in a dark age right now. Many of us who have long-time friends and relationships in Canada feel like Rick Blaine and Victor Lazlo in Casablanca.
I had the measles as a child before vaccines were available. It was the most sick I ever was in my life. I could have died if it were not for my mother watching over me. I have also had MMR boosters in the intervening years. I saw children in my grade school who had one leg shorter than the other the other who had to have one shoe with a very thick sole and steel braces to walk. When you see that as a kid you embrace vaccines. I did not get polio.
Do not believe the lies of Orwellian anti-vax fascists. War is not Peace. Ignorance is not Strength. Slavery is not Freedom. I appreciate my Canadian friends who realize that many of us in the US still retain our core values, critical thinking, and good will toward Canadians.
Once herd immunity drops below 95% immunizations, these diseases that were almost eradicated reemerge to kill and criple again. We are all in this together.
