A lot of people just stared accepting far right wing views like about abortion, LGBT hate and etc. Instead of fighting them. They also made a lot people really belive that all problems we face are not from big companies wo only pay minimum wage (which isn’t enough to support people in bigger cities) or who own over 70% of the real estate in Germany but because of left wing politics and immigrants.
