Yes.I consider it more of an almost nothingburger because meh jokes at the expense of people is par for course for the White House Correspondents Dinner.
Biden (and Obama etc) have done far worse in word and action regarding right wing media every other day of the year when it's not a joke.
But when such a nothinburger occurs but is targeted at a conservative, the leftists don't go "oh it's just a nothing burger, let's ignore it". Instead, they get mad and very vocal about it.
I think such apathy like you are exhibiting right now is one of the reasons why the conservative movements around the world just aren't as powerful or popular as they could be.
