What country are you originally from? I’m a first generation immigrant from South Asia, and in my experience, support for socially liberal policies in these communities is often based on compartmentalization. For example, Hindu Americans may support multiculturalism, insofar as they are religious minorities in a Christian majority country. But 70% also support Modi, who definitely doesn’t have a multicultural vision of India: https://theprint.in/india/49-of-indian-americans-back-pm-mod.... One rule for their own country, different rule for someone else’s country. Similarly, most Muslim Americans support gay marriage. But not in their own families: https://www.cnn.com/2019/05/28/us/lgbt-muslims-pride-progres....
That’s why liberals like immigrants. When they seek to change American culture, immigrants like my parents think “well let the Americans do what they want.”
