In late January 2020, then President Trump established a travel ban from China to stop the spread of the Covid virus to the USA. On Feb 1, 2020, then candidate Joe Biden tweeted,
"We are in the midst of a crisis with the coronavirus. We need to lead the way with science — not Donald Trump’s record of hysteria, xenophobia, and fear-mongering. He is the worst possible person to lead our country through a global health emergency."
Notwithstanding this later statement, the China related travel ban lasted until early November 2021 when it was ended by then President Biden. Then following information from South Africa on a new Covid variant, a new covid related travel ban was established in late November 2021 by Biden. This new travel ban is set to expire on December 31 also on the order of Biden.
This issues relating to the travel bans are quite complicated and the evolution of knowledge of the virus is also complicated and I'm not going to assign hypocrisy to Biden on this, although, for example, Juan Williams, the 'leftist' counter puncher on Fox, comes close to doing this.
What I want to do is think about whether hypocrisy can be 'undone'. That is, if we assign Biden hypocrisy for saying 'travel ban bad' in Feb 2020 and then issuing a similar ban in Nov 2021, could this hypocrisy be undone if the November 2021 ban was itself undone on December 31 2021. It seems to me that, no it would not be undone but it would be, in effect either 'made a smaller hypocrisy' or it would be evidence that the Biden motive of the ban in November 2021 was qualitatively different than the Trump motive in January 2020.
