First off Hills, nice to see you posting. I didn't see you much on the three boards I peruse and not going to lie, I was concerned. So, yay!Would you be cool with the next R president making you eat beef 3 nights per week because he believed it was what's best for you and had studies citing the health benefits of a diet that includes meat?? Even vegans?
To answer your question, like the abortion comparison, the crux is that this is a contagion. In the comparative examples your behavior really only impacts your behavior and your life at a general level. If me eating hamburgers all day made you and your family really sick....well that changes things.
Vaccinations are not 100%, they are just the most effective weapon that we have right now.
We're at war with a virus that's like a forest fire. We can put as much fire resistant material on our houses as we can but if 40% of my neighborhood is basically dry kindling and is going to be engulfed in flames, giving it more fuel, well my protection will probably get overwhelmed.
Which has always been the key in my pov. The more people protected makes it much harder for the virus to find hosts and spread.
