I am and have been a huge advocate for the vaccine. I am vaccinated with the mRNA vaccines as is everyone in my family. My kid is too young still but he has all other vaccines and gets the flu vaccine once per year.
I loathe the vaccine mandates. The issue I have is in abuse of power bordering on dictatorship. Our government is set up with coequal branches of government, each with separate enumerated powers. There are also independent levels of government with local, state, and federal scopes of power. Those advocating for Biden's ability to order vaccine mandates are trashing all of those limitations. Their argument appears to be that if any part of the government has the power to do a thing then Biden has that power. That is not how our government is supposed to work. That is how a dictatorship works.
Joe Biden did not get elected to be Dictator. Just because local school boards and state legislatures may have a power does not mean the head of the executive branch of the federal government does. No past US President executive ordered MMR vaccine mandates. The problem isn't the mRNA vaccine but instead the gross abuse of power.
