I know for a fact you still have a large portion of the population over here who would not care no matter what happened. As he so aptly said in the past he could kill a guy in time square and no one would care. He is honestly doing far worse than that an no one is batting an eye or they are excusing it away with their own facts or by attacking any opposition. Trump seems to be the sort of person who can't handle criticism or the possibility that he could be wrong occasionally. Unfortunately, future generations seem to share some of those same traits, so I fear it will only get worse.
I am glad that you mentioned similar traits of the younger generations, because I see it too. They are thin-skinned, and vengeful - looking to score points against perceived enemies, no matter the cost.
Not only is the behavior there, they are also getting validation for it with the current administration. It's really politics in general, the current admin just grandstands it more.
What happened to good role models in society...
Long long gone. Probably longer ago than we realize, they just hid it a lot better before. Some of them anyway.
The "hiding it" is important I think. These days, people are celebrated for their celebrity, not for their skill. It takes the focus of what they actually do well, and puts it on their private lives.
I genuinely see some really great role models on social media... but the problem is that the algorithms boost the terrible role models because conflict generates engagement... and the terrible role models also make a lot of money from selling dubious products or have wealthy backers.
So the great role models simply struggle to be heard even if their messages are overwhelmingly positively received... because they'll never be as profitable to the platforms.
There are probably good role models at the local level, but everyone consumes globally. Good parental role models aren't found on Instagram.
