Well, we've become so tolerant, we've forgotten that somethings are just not good, and it's become taboo to talk about certain things.
Certain ideologies are just not compatible with western culture, specifically those who condone raping women and murdering lgbtq people. Ideologies are not races or ethnicity, they are not inherent to you like race is. Nazis are an ideology, so why give other ideologies a pass?
Furthermore, immigration hurts the average worker. A person born into a poorer country will usually work for less than a person born into a richer country. Immigrants are basically scabs, cheap abusable labor, and that's why we let in millions into western countries.
Canadians can't buy a house, the UK can't get a doctors appointment, Germany elected the nazis in, Italy came close to electing fascists, Sweden is the rape capitol of Europe, and America is close to electing Trump again, wages are down every where, purchasing power is down, everything is fucked.
We've let in so many in the name of tolerance it causes problems that we aren't even allowed to discuss, and it's destroying our countries.
