All of this is IMHO so keep that in mind.
Politically it’s pretty extremist from what I can tell. Not just that but support for that extreme political stance is also rather high. Neithe of which is a good thing in my book. Other news I get to know about also tend to paint a pretty grim picture when it comes to human rights, rich/ poor divide and acceptance of people who have different preferences. I also mostly remember having met people how you described in the opening.
To say how it is, my opinion is not exactly good. Primarily because of how they act a d their political choices. Though I chalk some of that up to a lack of education. And it’s also not so bad that I’d rather not deal with them. Just that I have a healthy dose of " oh no, not one of those guys again. This will get exhausting, isn’t it" whenever I see someone that fits the description.
Real scenario: you wouldn’t see that happen.
Hypothetically it could cause economic collapse because now there wouldn’t be money to back up all the loans that are outstanding. Followed by mass layoffs of people and all the other fun stuff that comes with it.
