We are about to enter September and shots have been given to over 180 million Americans. There is an abundance of data on how the vaccine works and its effectiveness.Calling people stupid or ignorant is not going to make anyone get vaccinated. I would also add that some people may be hesitant because early on elected officials said they would not take the shot since it was under the former POTUS. I am sorry to say but that puts doubt in my mind. I just do not think name calling or shaming is going to help the situation from either angle.
You letting yourself be swayed by a politician from November is honestly quite pathetic when it comes to this matter.
There has been enough hand holding to show people that vaccination is safe and important. If you continue to ignore that then yeah be prepared to be called ignorant or selfish.
