One of Trump's faults was his public attitude towards the virus. Although it is worth pointing out that a press conference and gaffes are not the final word on the actual response e.g. "under control" is often mocked in hindsight despite it having been said while actions ---louder than words-- were taken to ensure it would be controlled.
Now about Tero' s claim, that Pelosi isn't fair game. It is, once again, simply more bullshit. One of Trump's faults was his public attitude. Why should another politician, one with even more influence than Trump in the public eye for many Americans escape blame if she had a similar attitude in public?
As for it being merely a distraction, again, more bullshit. Tero and Seabass are engaged in a rather absurd endeavor to blame Trump, not for everything, but it's fair to assume they think he can be blamed for a majority of what went wrong. It is reasonable then to examine what or who else might be to blame, and by how much, if only to more accurately measure by comparison Trump's blame...

....yes, you should think, how silly! What a stupid way to think! But that is precisely what it means to take this approach seriously. We are invited to consider by how much Trump is at fault. It only ceases to be silly if that's not really what Seabass and Tero intend to do, to have a serious discussion. They aren't inviting us to consider facts and to reason about what has happened and is happening. They aren't interested in uncovering reality. They're playing politics.
The latest fad is a poverty social. Every woman must wear calico,
and every man his old clothes. In addition each is fined 25 cents if
he or she does not have a patch on his or her clothing. If these
parties become a regular thing, says an exchange, won't there be
a good chance for newspaper men to shine?
