Provide any proof that he does this 50 times more than anyone else and I'll concede it. But right now, since you're pointing out logical fallacies, you're pulling made up numbers into your argument to try to prove a point. The thing is, Trump is under the highest level of media scrutiny, and if you haven't noticed, a vast majority of the media time he gets is negative. It might be information bias that makes you assume that Trump has done this "50 times" more than anyone else, when in all actuality, it is highly unlikely he has done this in 4 years more than people who have been in government for nearly 50 years (for instance Joe Biden who has been in politics for over 40 years).
I'm not telling you this to say Joe Biden lies more or backtracks more, because honestly idk who does, but I'm telling you this to point out the absolute absurdity of you saying Trump does this "50 times more" than anyone else, considering there's people who have served over 10 times longer in public office...
I agree it's not a good argument to say "a lot of people commit crimes" but that wasn't the point at all. I agreed with your statement about Trump, however, I am making sure that you recognize this is not uncommon in U.S. politics, because by the tone of your initial post, it felt like you were surprised to see a politician not carrying through on his/her promises... So it's not about disproving you (which is why I don't think this is necessarily whataboutism) it's more to make sure you understand this is no where near an abnormality in politics.
