No; the problem with Trump is the specific types of laws he broke. He broke laws around honesty, fair dealing, obstruction of justice, and, of course, the integrity of elections and our democratic process. He is, very plainly, opposed to democracy and the rule of law, preferring to replace it with cronyism and nepotism.
That's why he's bad for the country, not simply "because he's a convicted criminal."
True, but we're talking about expectations here.
I'm sorry, I'm not entirely sure what you're trying to say here.
Are you saying it's normal or acceptable to have your expectations be that a "convicted criminal" is automatically a bad person?
If so, then particularly given the large and very-well-documented racial biases in arrest, prosecution, and conviction for crimes here in the US, perhaps you should consider adjusting those expectations?
If not, then please actually say what you mean clearly.
I believe what the parent comment is trying to say is: someone who committed crimes in the past has evinced a lack of respect for the law, and is therefore more likely to commit crimes in the future than someone with a history of law-abiding.
"Bad person" is a value judgement, which is besides the point.
