Stupidity was going about your normal life, and getting mad about the new reality we were faced with when this whole thing started. The balance of risking your life for the sake of having fun was heavily skewed toward stupid.
Bravery is beginning to build a new semblance of normalcy in a post vaccine world, and attempting to move on. We have the science, we know it works, we just have to trust it now and be brave. The balance of risking a mild flu-like infection at worst for the sake having fun has flipped toward being brave for people who are vaccinated.
This virus is here to stay with us for the rest of the history of humanity. But we know how to beat it now and a fully vaccinated person is clinically proven to be at minimal risk.
