Multiculturalism - the premise that all cultures and lifestyles are of equal value and that one should not judge the other as inferior simply because they are not like your culture.
Preached as dogma by the Left in Britain and most of America so when these stories arise I ask the Left “who are you to judge what other cultures value?” If they value raping young girls and selling them as sex slaves, who are you, oh preachers of multiculturalism, to condemn them? On what moral authority do you declare yourselves superior?
Unfortunately, culture got equated with race, so criticizing culture was considered racist.
You cannot choose your race, you do choose your culture.
