Sure, happy to explain my reasoning. You said "I agree people should get the shot." Unfortunately, a lot of times that phrase is followed, either explicitly or based on context with the rest of the conversion, by "but it's their choice and I oppose mandates". The use of "should" that people use for "should eat right" not "should wear a seatbelt". It's gotten to the point that if I see such a phrase without specifying something like "everyone should get vaccinated", I assume it's an anti-mandate (and often antivaxer)
