Don't you know about the evil immigrants, ethnic minorities, and gay/lesbian-transgenders that are... checks notes just living their lives and not bothering anyone else.
Is this a serious question? People aren't really angry at other people, they are scared and angry about the situation their world is in. There's a few really bad apples, but most people are just scared they won't be able to pay their rent 2 years from now.
Thats why you can't give every party a fair chance. After what happened last time, Germany now practices what's called "Defensive Democracy" where parties that are considered anti-democratic can be banned (including banning all successor parties).
It's simply not right enough, considering there's free speech etc. laws. Even though some (many) members are straight up Nazis and openly express this, the party itself is technically not "too far"-right
Yeah well German politicians have really gone out of their way the past couple of years to make that happen. Setting off to tank the economy and self-righteously pushing away any and all criticism has never worked out well for anyone...
