How have you tried reasoning with the crowd.
A few examples.
By explaining the historical safety and efficiency of vaccines, some of which were developed and produced with less knowledge and expertise that we have now.
By showing statistical data of how so many more people have adverse effects from covid then from vaccines.
By showing the vast consensus of scientists/experts telling us that the vaccines work and are safe.
By explaining, through science and statistics, how their concerns are either completely invalid or vastly overblown.
And many others. However no matter how much accurate and factual reasoning is attempted it is "but this, or but that" and "what ifs" and I don't believe this source or that source.
Reasoning has been attempted for almost a year already and you get to a point where enough is enough. It's like dealing with a 3 year old. At some point you give up and take stronger measures. That's what is happening around the world. The world has given up trying to reason with the 3 year old mentality of the anti-everything crowd.
I am sure that you will be giving a "but, but, but" or "what if A, or B,or C" type reply or "I don't believe what you are saying" type reply. If you do, then you should be sent to your room with no dessert.
