I do believe the carrot works better than the stick, but I don't think this goes as far as being "treated like a threat".

I understand that you believe that unvaxxed are where the mutations happen.

I didn't say this and this is not my full belief :( . Mutations can happen at any new infection (including breakthrough infections, yes). So, the premise is to reduce new infections as much and as fast as possible. I think we're on the same page that vaccination greatly reduces your chance of infection (even more than having previously been infected before). Getting the most people vaccinated, as fast as possible, is the most efficient way to achieve that.

Overall, though, you've gotten pretty far away from the original question, "Well, what would it take for you to change your mind [to get the vaccine]?"
