Open carry is legal anywhere concealed carry is legal. It is legal for all adults unless they are prohibited from possession of firearms. Wisconsin state law 948.60(2)(a) states: “Any person under 18 years of age who possesses or goes armed with a dangerous weapon is guilty of a Class A misdemeanor.”
Polio had a VACCINE. Covid shots are NOT a vaccine. If they were, people would be immune. They are not. People with shots are still getting Covid. The shots are a treatment that helps tell your body how to deal with Covid, it does not make you immune.
I agree the cartoon was not meant to be funny. @NeoconMan was out of line.
