Make it a default, not a mandate.
A vaccine default is a great solution, Wayne. In regard to another issue, namely the issue of veganism, becreaturekind.org is achieving positive dietary changes via defaultveg.org
You're right, that's a great solution. Those who really are against taking the vaccine would jump through hoops to not get it. And those not as serious would give in. Makes sense. But unfortunately, the people in power don't want a solution. They want exactly what's going on right now: people bickering at each other. Divide and conquer, that's how they keep power over us.
Nobody should be coerced or punished in any way regarding vaccines. Nobody should have any right to anyone else’s medical business. Double Vaccinated folks are still getting the virus, spreading the virus, and dying from the virus. People are being injured, and dying from the vaccines as well. There are many different reasons people have for deciding to get vaccinated or not vaccinated, and it shouldn’t be anyone else’s business what their reason is. Nobody should have to prove anything to anyone else as to why they don’t want to take something that is potentially harmful, let alone for something which has potential benefits that wear off in a matter of weeks.
