Does the fact that up to a half of all Americans  would refuse a Covid vaccine ,show how dumb America has become in recent years?

Someone would have to be pretty dumb to refuse a vaccine. The vaccine is the gateway to not get covid and also go back to normal. 

America is known for being loud, the opposite of dumb

You are leaving out a lot of context. 

Kamala Harris said that she would not take a vaccine if Trump recommended it....

...but it's "cons" that always make things about petty politics....... right?

Look, I know that democrats want to force people to buy a specific product, especially if it's from a prominent DNC donor, but competition is good.  Maybe you shouldn't be going out and celebrating a Biden victory without social distancing if you're really concerned about a virus that only 98% of us will survive without vaccination.  

Trump supporters are proof the countrys IQ has dropped durasticly. Its why non college voters are his base. They litterally are statisticlly speaking lmao.

I am not taking any vaccine nor obeying the government or these corporations run by elitist thugs
