If it was only Trump's constant complaining about one thing? Then fine... he has one issue, and can't get past it. However, it isn't just one thing that he whines about. It's 7 or 8 things. Trump has also whined about such silly things as :
(1) Being passed over for Time's "Person of the Year" in 2018... even though, he had already been named it in 2016.
(2) Not winning a Nobel Peace Prize.
(3) Reports that his 2017 Inauguration was not as heavily attended as Barack Obama's from 2009.
(4) Not winning the popular vote in the 2016 Presidential Election. A meaningless designation, but in his mind, evidently a big deal. Of course, he had to allege that it was just the result of massive voter fraud.
(5) Losing the 2016 Iowa Caucuses to Ted Cruz. He accused the Cruz Campaign of cheating, without ever explaining how they had cheated. He went on with that narrative for months... even after he had already won the Republican Party nomination.
(6) The bias of Google's algorithms... Does anyone even think Trump would be capable of comprehending the algorithm if someone was able to hold his attention long enough to explain it to him?
(7) His Twitter ban.
This isn't fighting back. This ^^^^ is called whining.
